Abstract
Finite element method (FEM) modeling of the island blister test (IBT), which takes into account the possibility of plasticity in the film an d can separate the normal and shear components of the specific fractur e energy, is presented. IBT specimens of a polymer film (Ultradel 4212 ) on a chromium-coated silicon substrate were prepared and tested usin g modified procedures which am described. The analysis of the experime ntal results shows that crack propagation occurs when the mode I compo nent of the specific fracture energy reaches a critical value.
