Impact Analysis using ADINA ADINA 에서의 충격해석 Presentation Overview
※ Types of impact: crash and crush ※ Failure mechanisms ※ Equations to be satisfied ※ Impact analysis with finite element method ※ Example: Rod impacting a rigid surface ※ Modelling recommendations ※ Advantages of implicit time integration for impact analysis
Example of a Crash Impact Event 
※ Deformations magnified by factor 6.6 ※ Contact traction reaction vectors to visualize initiation of stress wave ※ Unsmoothed band plot (no averaging of stresses)
• Occurs over a time scale considerably longer than the time for a stress wave to propagate through the structure (typically in the order of seconds for steels)
• Can be analyzed quasi-statically
• Wave propagation is not important. Impact duration determined from geometry, loading and boundary conditions. It is not dependent on stress waves propagation
• Example of crush event: crushing of motor vehicle roof or door, crushing of impact tube, etc.

USA standard FMVSS 214 specifies minimum crush resistance for car door, based on quasi-static test where rigid steel cylinder is pushed into car door. 자세한 내용 pdf 파일로 [ 자세히 보기 ]
