A theoretical analysis is proposed to predict the out-of-plane tearing response of rectangular plates with two or three legs. The nonlinear differentiate equation for deformation and the double linear strain-hardening constitutive relation for bending moment against curvature are used in the analysis. The external work is assumed dissipated through the bending deformation of the legs and the crack propagation at the tip of the crack between the legs. A good agreement has been achieved between the theoretical predictions and the experimental results for the variation of external force with displacement. It has been found that the variation of bending force with displacement significantly depends on the strain-hardening modulus and the tearing force.
