Dent Test Simulation

Hood Outer Dent Simulation

• Dent simulation provides important guidelines for exterior body panel down gauging to achieve weight reduction
• Forming effects are considered using hybrid explicit and implicit FEA
• Compare lab dent test results with simulation to improve CAE predictability
• Simulations can be performed to evaluate various methods of improving dent resistance, such as:

1.  High strength steel application
2.  Geometry changes to improve stiffness
3.  Local reinforcements
4.  Influence of panel stamping strain
