Abstract

Solutions to mixed mode problems for plates under bending, with inclined through-the-thickness cracks, are obtained taking the closure phenomenon on the compression zone into account. A three-dimensional finite element method using singular and transition elements to model the crack tip region is employed for the analysis. The closure region on the crack faces is determined by a trial and error procedure. An attempt is also made to determine the influence of frictional forces between the interacting crack faces on the stress intensity factors.
