FEMとBEMの結合モデルと接触問題への適用

概要

論文の詳細を見る
A combined model of FEM and BEM is proposed and formulated for plane stress problems using the same concept in the rigid-body spring model (RBSM). The proposed simple bond elements are applied to the problem of uniaxial tension of a rectangular plate with a circular hole which contains a circular disk with the same initial diameter as the hole. The plate is divided into boundary elements in the BEM and the disk into finite elements in the FEM. The simple bond elements are introduced into the plate-disk interface. The normal stresses on the contact arcs are compared with those determined using an exact elastic analysis and the FEM. The combined model proposed here is found to be effective for contact problems. The contact problem of a cantilever with a built-in wall is also analyzed by this method, and the elasto plastic behavior of the cantilever is analyzed.
