Abstract :
According to voice of engineering, 3 dimensional condensation boundary element method is used to solve multi-body frictional elastic contact problem. Frictional elastic contact problems belong to local nonlinearity problems, the relative sliding of contact face gives rise to energy dissipation, in this paper, incremental method is adopted to trace the whole course of loading, condensation method is used to realize the solution of boundary matrix equation. Taking three bodies frictional elastic contact model for example, the establishing of boundary integral equation and the solving process of boundary matrix equation are illustrated. One calculation example is given to prove the validity and high efficacy of this method.
