An asymptotic procedure and numerical study for the analysis of an elastic body with a thin sub-surface crack
Published online by Cambridge University Press: 26 September 2008
Abstract
A class of three-dimensional crack problems is considered, of which a prototype example is provided by a half-space containing a long internal crack, located in a plane perpendicular to the boundary. By means of an asymptotic procedure, the original three-dimensional problem is split up into a sequence of two-dimensional formulations. Results of its numerical implementation are in good agreement with results of more computer-intensive finite-element calculations.
