This course introduces the fundamentals of FMVSS 216 and FMVSS 216a Roof Crush Analysis using an existing NHTSA LS-DYNA model. It is designed for mechanical engineers, CAE engineers, and students who want to understand the engineering principles behind roof strength evaluation and rollover safety.

The course covers the intent of the regulation, physical test setup, loading methodology, boundary conditions, and performance requirements. Learners will explore the complete LS-DYNA model in LS-PrePost, understand how the simulation is organized, and learn a systematic approach to post-processing, including deformation analysis, stress and plastic strain evaluation, reaction force interpretation, roof intrusion measurement, contact verification, and energy balance checks.

By the end of the course, participants will be able to confidently interpret roof crush simulation results, understand structural load paths, and identify opportunities for lightweight and safer vehicle design using CAE
