Simulate a drop to the ground or against other structure to see if your product withstands the loads without unacceptable damage or deflections. During impact, the deflection may damage internal parts or cause intrusion of water or dirt/dust.
The part/product being analysed can range in size from a small metal piece or an electronics device to a large container, or even a ship hitting the harbor at high speed. Simulating a drop test, in reality, is normally very costly and time-consuming. Nastran In-CAD can help to simulate drop test virtually.
Symetri can also help you via consultancy in the event you are under tight timescales.
