G031106 Identification of material constants on the inelastic deformation of the Capsule-Chuck under internal pressure

Abstract

The Capsule-Chuck is well known chucking system to grip a roll in the Converting industries. However, mechanical properties of the Capsule-Chuck are not clarified yet. Mechanism of this chuck is expanded polyurethane elastomer which is called the Capsule under certain air pressure. In this research, new method to determine material contents both elastic deformation and inelastic deformation of the Capsule is proposed.
