COLLISION IMPULSE DERIVED DISCRETE ELEMENT CONTACT FORCE DETERMINATION ENGINE, METHOD, SOFTWARE AND SYSTEM

摘要

A method and engine for simulating a multi-body system, the method or engine including code for determining collision impulse over a time period for a plurality of colliding bodies in the system. An admissible function is determined from the collision impulse and resembles true contact force from the collision impulse. Complete contact force change during collision is derived from the admissible function.
