✦ Synopsis

continuous analysis procedure is introduced for determining the strain-energy release rate for composite plates containing arbitrarily located delamination regions of arbitrary shapes. The plates are considered to be simply supported along their four edges, and double Fourier series solutions'are used. A simpler case for a symmetrically loaded double identical plate system having mid-plane delamination resulting in mode I deformation is studied first, and the general case involving the determination of all three modes of the strain-energy release rate for a system of two orthotropic plates bonded by a layer of adhesive is considered subsequently. Some numerical results are presented for illustrative purposes.
