Sustainable Packaging: Beverage and Home Care Bottle Development by V-Pack (Virtual Simulation, Optimization for Blow Molding)

The Rigid packaging market is expected to witness significant growth. India rigid plastic packaging market stood at USD11.54 billion in 2021 and is anticipated to grow at a CAGR of 8.01% in the forecast period, 2023-2027*. High demand for rigid plastic packaging from the healthcare, pharmaceutical, and food & beverage industries is the major driving factor for India's rigid plastic packaging market.
There is a continual sustainability and economic drive for minimizing plastic content. The focus has shifted to designing lighter-weight versions of current packaging to downsize for more sustainable products.

RIL MEC V Pack studio's development methodology has been complemented by 3DS Similia’s simulation and modelling capabilities. V-Pack (Virtual packaging) is an effective tool to optimize both blow moulding process and part design to yield desired bottle performance at a minimized weight in an accelerated manner. It helps to validate concept designs early in the development cycle, reduce the number of physical prototyping and hence significantly reduce the product development time

The objective being to predict the design should meet all the desired CTQs. Unlike injection molding, blow molding inherently has challenges providing a controlled a uniform thickness distribution because every region stretched differently so the challenge for material/thickness distribution over the bottle design to achieve required performance with optimized weight and cost. 
We were successfully able to simulate, predict and corelate with physical sample testing of Home care bottle design in EBM (Extrusion blow molding, HDPE) and Beverage bottle design in ISBM (Injection stretch blow molding, PET). Process simulation in this study guided part filling/forming behaviour and helped predict the material/thickness distribution in blow molding process. The final material distributions were mapped onto an FEA structural model, which was further able to replicate real-world usage/loading scenarios in manufacturing, consumer handling, distribution cycles (supply chain/logistics). The evaluations were aimed at the ultimate objective of delivering a product safe for final consumption.

Using RIL’s V-Pack Studio methodology and 3DS-Simulia products, the team was able to establish right-weighted sustainable rigid packaging products for the Beverage and Home Care bottles. The process and structural prediction helped optimize several parameters to establish optimized bottle wall thicknesses, weight, and shape aspects, whilst achieving a top load strength enhancement of 25-30%, prior to final tooling freeze.

Evaluation of Weld Health Using Verity for Automobile Components

Structures in fields of automobiles, aerospace, marine, defense, energy – appliances, etc… are generally combination of system of components well organized and connected (fastened).  One such critical fastening methodology is welding technique, which is permanent fastening technique to keep them integrated. Assessing the health of these welds becomes crucial to determine life of all these structures.

In automobile industry, the components are fastening by various weld techniques keeping in view both structural integrity and structural reliability. Assessing life of such welds become important to determine the quality and warranty period of the vehicle. These welds can be assessed in numerous ways, and one of the most promising methodology is by Structural Stress method (SS). Verity is based out of the Structural Stress method, developed by Battelle Laboratories by Dr. P. Dong.

Structural Stress method utilizes the nodal forces at the joineries (roots and toes) to compute the structural stress (SS) of the components. Upon computing these SS’s, they are mapped over the SN curves database spanning from early 1950’s to till date. The SS method uses the nodal information, but is insensitive to the mesh quality and size. Using this advantage of mesh insensitivity, Verity is capable of assessing all types of welds (including spot welds) under all loading patterns.

Current work focusses on few automobile case studies, where welds were assessed through Verity. Critical welds locations were identified through this evaluations and design modifications were done for robustness. Similarly few fail-fail and pass-pass correlations are also presented and found the life predictions through Verity were much realistic (as in line with Lab test) when compared with other commercial fatigue tools.

Johnson-Cook model calibration for brittle materials under impact loads

In the assessment of parts subjected to impact loading, the current process relies on static analysis, which overlooks the significant influence of high strain rate on material hardening and damage. The omission of these effects hinders accurate impact simulations, limiting the analysis to comparative studies of two components and potentially misidentifying critical hot spot locations. To address these limitations, this study emphasizes the importance of incorporating the effects of high strain rate in impact simulations. By utilizing the Johnson-Cook material calibration model, which includes both material hardening and damage models, a more comprehensive understanding of material behavior under dynamic loading conditions can be achieved. The Johnson-Cook material hardening model accounts for the strain rate sensitivity of the material, providing an accurate representation of its behavior under high strain rate conditions. This allows for improved prediction of material response, particularly in terms of plastic deformation and flow stress. Additionally, the Johnson-Cook material damage model considers the progressive accumulation of damage and its influence on the material's failure behavior under impact loading.

Simulation, Correlation and Resolution of Bogie Suspension Rubber Bush Housing Failure Using Hyper-Elastic Material Model

In many cases, FE-based evaluation of rubber components is a challenging task since rubber has highly non-linear behavior and contact issues are associated with rubber movements, which make FE-based evaluation challenging. Therefore, specialized numerical methods and models are needed to accurately capture the behavior of rubber components in order to predict their response. To achieve reliable predictions, these specialized models must be accurately implemented in FE-based simulations, providing a reliable and valid evaluation of the rubber components. To ensure accurate predictions, it is paramount that these specialized models are implemented correctly within FE-based simulations, allowing for a reliable and valid evaluation of the rubber components. Furthermore, contact issues between the rubber and any other components must also be taken into account, which further complicates the FE-based evaluation.

In the Tipper vehicle Bogie suspension, it has been reported that the rubber bush bottom housing failed at an early stage in the field. This assembly involved Rubber bush mounted on Trunion shaft and Top and Bottom housing is connected through bolts. This failure is thoroughly investigated and FE analysis methodology is decided. We modelled the rubber bush in an uncompressed state and solved the assembly process as an interference problem using hyper-elastic material properties. As a result of the high rubber bush stiffness, the Top and Bottom saddle joints are opening. This opening resulted in the bottom saddle experiencing variable loads. The variable loads caused the bottom saddle to fail under high loads. To overcome this issue, multiple iterations involving modifications in bottom saddle design, changing friction in the assembly process etc. This work illustrates the capability of Abaqus to solve complex problems involving material and contact non-linearities which resulted in early resolution of the field failure issue. The use of Abaqus in this process allowed for a simulation of the design, which was a crucial step in understanding the behavior of the system and resolving the field failure issue.

Simulation Techniques for Liquid Gasket Sealing Performance Prediction

In the automotive industry, silicon adhesive has become increasingly popular due to its benefits in ease of assembly and cost savings associated with material and manufacturing processes. Due to the demand to reduce time and costs in the development phase of the project, it is critical to choose the right gasket material, and a suitable flange design as early as possible in the design process. In order to achieve stringent emission standards such as Corporate Average Fuel Economy, a better sealing performance is an essential parameter. Various types of liquid gaskets such as silicon rubber based Room Temperature Vulcanizing sealants and thermoset plastic based anaerobic sealants are widely used in an Internal Combustion engine. They are commonly used for the components such as oil sump, bedplate, gearbox housings, etc. Traditional simulation methods could not capture the exact failure mode of the liquid sealant. Hence there is a need for a better understanding of the factors controlling a joint's sealing performance under realistic service conditions. This paper describes a methodology to predict the sealing performance of liquid sealants at a very detailed level. An innovative 2 Dimensional and 3 Dimensional simulation approach is used for micro level modelling of the joint. In the first phase of the simulation, a 2 dimensional simulation approach is employed for predicting micro level joint behaviours under various initial conditions. In the second phase, a 3 Dimensional approach is applied to find the behavior at the global level of the joining surface. Final sealing performance is evaluated by combining the 2 Dimensional and 3 Dimensional simulation results. Experimental validation for the most commonly used liquid gasket was carried out to establish the correlation of this process. It has been found that the predicted sealing results are well correlated with the experimental findings.

Fatigue Life Prediction of Fibre Reinforced Plastics Using Multiscale Modelling Approach

Use of composites requires detailed understanding of the composite behavior and new design approach. Composites design and development requires a dedicated approach in order to take into account the complex material behavior. Randomly oriented fibres in composites exhibit anisotropic, heterogeneous and Complex nonlinear material properties. Material response of composite is sensitive to local fiber orientations, nonlinearity, as well as strain rate dependencies, which relies on the manufacturing process of the part. 

In fatigue tool, Based on few macroscopic S-N curves, it enables to predict the S-N characteristics for any orientation state of the fibers. So the combination with local fiber orientations yields a fully coupled approach to predict the fatigue life. Such analyses takes into account the local material performance based on the microstructure information and thus represents actual distribution of material properties as found in reality. 

This study aims to bridge the gap in order to predict more realistic life of component by using multiscale approach. The fiber orientation output of mold flow simulation is mapped in the structural analysis using mapping tool. This process involves generating discrete material data card by combining basic nonlinear material data and fiber orientation data from each element. A study on Bumper carrier assembly is carried out using Abaqus, material test data is used to develop the advanced material model in CAE simulation. Correlation with fatigue test results will be shown.
