• A special crack element for the analysis of cracked plates subjected to out-of-plane bending, twisting and shear is developed based on a hybrid finite element model. Equilibrated stresses within a crack element are derived by making use of a complex variable method and Kirchhoff plate theory. An infinite plate containing a through crack subjected to transverse flexure is analyzed in order to investigate the accuracy of the stress intensity factor solutions, and the effects of element size and the number of stress parameters. The well-known analytical solutions for this problem are reexamined and correct solutions are provided. Other numerical examples include typical crack problems of a plate of finite dimensions under transverse flexure.
