Abstract

The objective of this paper is to extend the hybrid mongrel singular element approach to the computation of stress intensity factors for a cracked plate subjected to out-of-plane loading. Reissner-Mindlin plate theory was selected for transverse shear effect. The stress intensity factors were directly computed by the stress unknown parameters or indirectly by new developed formulae for a square cracked plate under uniform edge bending moment or transverse pressure loading. The effects of geometric boundary conditions and Poisson's ratio on the mode I and III stress intensity factors were investigated. Very good agreement with the existing solution in the literature was shown for the plate without crack as well as cracked analysis.
