Description
Summary:This paper is concerned with the plane elastostatic problem of a crack emanating from an open notch where it is assumed that the crack is directed parallel to one side of the notch. The problem is reduced to two simultaneous Fredholm integral equations which are then solved numerically for free loading conditions of the crack faces. In particular, it is shown that the crack tip intensity factors are almost independent of crack length if the singular stress field associated with the uncracked notch is used as the loading of the crack faces.
