The influence of soft lining materials on pressure distribution

Abstract

Several soft lining materials are available at present that differ in physical and mechanical properties. To examine the feasibility of soft lining materials used as so-called “tissue conditioners,” the properties of soft lining materials were investigated by using a static creep test and a pressure distribution test. Six typical materials were used. The pressure on the testing plate was distributed uniformly on the soft lining materials. The soft lining material acted as a cushion for the external forces. However, the variation of pressures increased with time in the cases of Hydro-cast and Softone materials, but decreased with time in the case of Coe-comfort material.
