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 ...

Spot welding is a very common process used to join sheet metal components in the automotive industry mass production environment. Recently, thermoplastic composites as light weight alternatives to metals have begun to make their way ...

European LS-DYNA Conference 2015 Session # 1-1 A finite element investigation into the continuous induction welding of dissimilar material joints Miro Duhovic, Martina Hümbert, Peter Mitschang, Joachim Hausmann Institut für ...

In non-linear fracture mechanics, an energy based criterion is used for assessing the risk for crack growth: if the energy release rate at the crack tip exceeds what is required for creating new surfaces in the material, crack growth ...

The analysis of residual stresses or distortion of welded structures requires a welding structure analysis. This kind of analysis incorporates some specifics compared to other FEM-simulations. Apart from the definition of geometry ...
