Abstract

The problem of crack extension in brittle materials under general loading conditions is investigated. Methods of solution of the related two-dimensional elasto-static boundary value problem are discussed. Using Kolosov-Muskhelishvili stress functions, an approximate solution is obtained. The effect of the approximation on the results is estimated by solving two related problems exactly. Then using two postulates the critical loads and crack extension direction are determined under loading conditions unsymmetrical to the crack axis. Results are compared with those obtained using a different set of postulates.
