FINITE ELEMENT CALCULATION OF STRESS INTENSITY FACTORS USING SUPERPOSITION

A new approach to the finite element technique for calculating stress intensity factors of cracks is presented with the aid of analytical functions in the formulation, in which the total displacements of the conventional finite element method and the unknown constants of the analytical solution are determined in the modified principle of virtual work. The simple problem of a square plate with a central crack subjected to in-plane tension is solved and compared with the available exact solutions.
