Flexible Multibody Dynamics in Crash Analysis
The design requirements of advanced mechanical and structural systems exploit the ease of use of the powerful computational resources available today to create virtual prototyping environments. These advanced simulation facilities play a fundamental role in the study of systems that undergo large rigid body motion while their components experience material or geometric nonlinear deformations, such as vehicles in impact and crash scenarios. If in one hand the nonlinear finite element method is the most powerful and versatile procedure to describe the flexibility of the system components on the other hand the multibody dynamic formulations are the basis for the most efficient computational techniques that deal with large overall motion. Therefore, the efficiency of the nonlinear finite elements to handle the system deformation can be combined with advantage with the representation of the system components large overall motion using a multibody dynamic approach.
