Abstract

Mechanical properties of a thin circular flexible membrane are directly measured by applying an external load to the film center via a rigid spherical capped shaft. Constitutive equations are proposed for the shaft-loaded blister configuration based on linear elasticity. The dependence on the ratio of shaft radius to blister dimension is reflected in the load versus shaft displacement relation.
