Measurement of elastic response and delamination behavior of thin film-substrate system by a shaft-loaded blister test

摘要

We present a theoretical study of the constitutive relation for the shaft-loaded blister configuration in the presence of tensile residual stress. The relationships among strain energy release rate, load, deflection and residual stress are fully investigated. A series of numerical simulation and experiments allow us to verify the theory quantitatively which ought to have significant implications in many technological situations.
