摘要：

Straight-sided delamination of a thin, elastic film from an elastic substrate is analyzed. The loadings causing delamination are general in-plane stresses and a normal pressure on the film. Delamination is modelled as a crack propagation at the film/substrate interface and closed form expressions have been derived for the energy release rate and its separation into mode 1 and mode 2. The range of validity of these results is investigated by performing a stability analysis for the delamination shape considered. The results, which are related to both buckling delamination and blister tests, show strong dependence of the stability behaviour on the in-plane loading.
