This analysis steps through the real time of a dynamic load event allowing materials to strain and yield, loads to redistribute, contacts to be made and inertia to be transferred.

Impact analysis is one of the main applications of this technique. The non linear geometry and material capabilities allow the large deflection and plastic collapse to be modelled. The event could be controlled as with a golf club hitting a ball or unpredictable as with a drop test or an aircraft bird strike. We can assess the effect on the structure and optimise it for strength, mass or energy absorption.
