The strength of a finite body with multiple cracks

Abstract

This paper presented an analytical-numerical solution of a finite body with multiple cracks. According to the Bueckner method and based on the solution for the integral equation system of fracture series, we proposed a direct method considering interaction between boundary and cracks—“Virtual loading method”. Instead of repeated loading and tedious computing of non-equilibrium stresses on the boundaries, a direct analytical solution including virtual loads is used, by which the more accurate results are obtained and less computing time is needed.
