The purpose of this project is to improve the development process of vehicle safety systems by introducing a new analytic approach. Today the development of vehicle safety systems, especially the airbag design process, requires many ...

This paper describes geometry parameterization of turbine blade fir tree root prepared in LS-Prepost. The generated FE model utilizes LS-OPT in optimization loop. Simulation results of LS-DYNA implicit solver were used to extract ...

When deep drawing the parts with complex geometry, changeable thickening can occur in the flange area. Extreme thickening of the part flange will cause pressure peaks at the contact surface between blank holder and part. This ...

Dome reversal pressure test is one of crucial quality tests required of such products as beverage cans. It gives information about resistance of a bottom in conditions of increased internal pressure. The information is important both ...

Statistical studies showed that the chin bar of full-face helmets is the region with the highest number of impacts. In an Australian research fifty percent of severe impacts took place to the front of helmet and forty percent of these ...

This work presents results obtained from numerical analysis of ironing with use of finite element mesh. The base drawpiece, that was a starting point in the analysis, includes a full history of deformation that resulted from ...

Employing cohesive zone elements in the simulation of delamination in highly-loaded composite structures presents an incompatibility between the required length scales to accurately predict delamination (typically ~0.1 mm) and large ...

The future of automobiles will be driven by lightweight structures and highly efficient powertrains. The TARF-LCV EPSRC funded project (Towards Affordable, Closed-Loop Recyclable Future-Low Carbon Vehicle Structures) aims to provide a ...

LS-PrePost is an advance pre and post-processor that is delivered free of charge with LS-DYNA. It is designed and developed specially to support LS-DYNA in pre-processing and post-processing all in one single code. The main features ...

Material 34 (MAT_FABRIC) in LS-DYNA is the material model of choice for fabrics when simulating airbag deployment in the automotive industry. Over the years, the model has been subjected to continuous robustness improvements and ...
