    Abstract

    The interfacial shear stress is obtained in a plated beam using cohesive zone integrated analytical method. The shear stress distribution is obtained in elastic and elastic-softening zone. The plate- end debond initiation along with debond load is calculated using higher order theory including the transverse shear deformations of both the beam and the plate. The closed-form expression for interface shear stress is used to estimate the influence of different material parameters on the length of the softening zone and debond initiation. A complete solution for debond initiation is presented for the case of a simply supported beam along with the general formulation of the governing differential equations for the interfacial shear stresses and the results are verified with literature values.
