【Abstract】 The coupled boundary integral equations for the multi body contact problem with friction in 3D elasticity and the criterion for correct contact state are derived in this paper.The programs of isoparametric quadratic boundary elements for solving the multi body contact problem are organized.Compared with Heltz’s solutions,the results have proven to be reasonable and satisfactory.At last,the contacts of the high voltage composition insulator connection construction are studied.更多还原
