Abstract

Finite element models of hole-structure are built for analyzing hole-edge contact problems under thermal loads. In order to obtain accurate and reasonable numerical results, elastic model and elastic-plastic model are built in gradual improvement. In order to eliminate the influence of clamped support, a kind of artificial elastic boundary is proposed for simulating the boundary of hole-structure. Numerical experiments show that elastic-plastic contact model with the elastic boundary is reliable and applicable for finite element analysis of hole-structure.
