THE CALCULATION OF STRESS INTENSITY FACTORS USING THE FINITE ELEMENT METHOD WITH CRACKED ELEMENTS

The calculation of stress intensity factors for complicated crack configurations in finite plates usually presents substantial difficulty. A version of the finite element method solves such problems approximately by means of special cracked elements. A general procedure for evaluating the stiffness matrix of a cracked element is developed, and numerical results obtained by the simplest elements are compared with those provided by other methods.
