Mapping Deep-Drawing Simulation
Applications based on ANSA to the BMW CAE processes
Composites Modeling
MAPPING DEEP-DRAWING SIMULATION THICKNESS AND HARDENING RESULTS
Influences on crash simulation
Using the deformation history of the material as input in a crashsimulation, provides significantly better simulation results (deformation and cracks) and helps to reduce material consumption and to optimize the weight of the part
Crash-Simulation (mesh and results)
mapped thickness distribution
Stamping-Simulation (mesh and results)
thickness distribution is displayed
Crash-Simulation (body with stamping results)
degree of hardening is displayed

Disadvantages
• Convertible hood “only“ consists of independent parts (Dead GEO) • Connections are “not” converted (CAE) acceptably • CAE starts again right from the beginning • Every modeling step by hand
