On a Hybrid Approach for Modeling and FEM Analysis of Body Collision in an Engineering Application

A methodology for hybrid modeling and FEM analysis of body collision is presented and illustrated by a simpli ed, theoretical example. Each step required to use the presented approach in engineering practice is described and methods of checking the correctness of conducted FEM analysis are given. The in uence of colliding body configuration on the value of maximal collision force is studied and discussed. The results of FEM analysis, using the suggested approach, supported by free software, are presented and their correctness is veri ed by proposed checking methods. Advantages and disadvantages of the proposed approach are also discussed.
