Apparatus for determining material processing characteristics

摘要

An apparatus for testing the processing behavior of a visco-elastic material. A first ram is adapted to apply to a test sample a predetermined pre-test deformation. A second ram is adapted to subsequently apply to the test sample an additional test deformation. The first and second rams are disposed such that their respective piston displacement directions are parallel, whereby both the pre-test and the test deformation are compressive. A control system monitors the load relaxation in the test material.
