摘要

This paper provides comprehensive relationships for pressure, deflection, energy releasenrate, and phase angle for bulge testing, which are valid for all combinations of the testingnlength-scales (film thickness, debond size, and bulge height) and materials. These solutionsncan be used to design experiments that vary relative contributions of opening andnsliding displacements at the crack tip by modulating the film thickness, debond size, andnbulge volume. Their closed-form nature greatly facilitates property extraction via regression,ne.g., modulus from experimental pressure/deflection data or interface toughnessnfrom debond size/injected volume data. This is illustrated using experiments to quantifynthe interfacial adhesion energy between an initially dry polydimethylsiloxane-glass interfacenvia bulge testing under controlled volume injection. The results indicate that thenmode-mixity has no effect on the energy required for debonding, which suggests thatnwetting of the crack faces behind the debonding front eliminates friction.
