| Abstract: | The relationship between the tendency for growth of a delamination in a layered material and the presence of out-of-plane displacements due to Euler instability of the delaminated plies, is examined. By considering the work done by an external load, an improved expression for the energy release rate, G associated with a layered isotropic plate containing a through width delamination and subject to in-plane compressive loading, is derived and compared with finite element and experimental results. |
