Material Properties for TR-55 and Silicone Elastomeric Cushions

摘要

The notation of finite elastic theory for compressible rubber-like materials is introduced. The mechanics of data reduction, needed to determine the parameters of the theory, are displayed. the material properties of TR-55 rubber and silicone rubber cushions are obtained. The constitutive relation, with the material properties, correlates all uniaxial compressive data to a high degree of accuracy. The force-deformation relations of thin sheets of TR-55 in compression have been obtained. Further studies, both theoretical and experimental, on TR-55 thin sheets are needed to determine the force-deformation relation. 11 figures. (ERA citation 08:024033)
