6) Modify program CRSS to input Km stresses and displacements. 7) Use program CRSS to find the distance r at which σχ has some fixed value by trial and error. Can you alter the program to find this distance directly ? Find such a distance for a range of angles and plot the contour of constant stress around the crack tip. 1 Introduction The stress intensity factor K is a measure of the severity of the defect in a given cracked region and its determination is normally the first step in the process of deciding the maximum allowable crack size or stress.

It is important to realise that values obtained using the methods in this section are approximations. The effect of interacting boundaries may be highly significant. 23 with a corresponding change in SIF. 32 times the applied stress. Before tackling 'real' problems it is necessary to build up some experience solving problems with known solutions to discover what constitutes a reasonable approximation. 4 Numerical methods The analytical solution of elasticity problems is only possible in a few simple cases.
