✦ Synopsis
paper presents a method of analysis of doubly symmetric plates with a central crack subjected to symmetric concentrated forces at points on the outer bout&y. The problem is treated by using complex stress functions appropriate for the &action free crack and by means of a kiod of boundary coIlocation method. The method is also valid for ahitrwy load@ problems, since the applied loads can be replaced by concentrated forces so far as the crack tip stress intensity factors are concerned. Numerical examples are given for elliptical and rectan~rr plates and plates of other co&urations of practical importm~. Results of nctsalulpr plates give informatioos on experimental estimation of crack tip stress intensity factors in compkx structures.
