ABSTRACT:
A system for hydrostatically measuring the volumetric deformation of a crushable foam includes a test chamber that is in fluid communication with a pressure fluid reservoir. A sample of a crushable foam is loaded within the test chamber within a latex pouch and the pressure fluid is pumped into the test chamber in order to subject the foam sample to triaxial loading. The volumetric deformation of the crushable foam is continuously monitored through suitable electronics as a function of pressure within the system.
