Abstract
A circular silicone sheet is clamped at its edge and pressurised by the injection of a liquid beneath creating a pocket. We study experimentally the deformation and pressure increase caused by the compression of a pressurised pocket. Excellent agreement is found between experimental observations and numerical predictions based on an axisymmetric thin hyperelastic material; an approximate analytical model explains the link between changes in shape and the applied force.
