Abstract
The use of the traction boundary integral equation (BIE) for the analysis of three dimensional cracks embedded in an infinite medium is discussed. A general solution algorithm for non-planar and multiple cracks modeled as a patch of plane elements is presented. The procedure is based on a set of "regularized" traction integral equations, with kernel singularity reduced to O(1/r^2) through integration-by-parts, and on the use of local coordinate systems.File in questo prodotto:
