Boundary Element Analysis

In this paper BEM for analysis of fractured stiffened panels repaired with riveted patches is presented. Several boundary element formulations involving the membrane and bending of displacement, and, stress resultants are coupled together to analyse the model. The Crack Opening Displacements (COD) method and the J-integral are implemented to evaluate the required fracture parameters.
