Abstract
A system for testing various properties of a viscoelastic material includes a balanced beam supporting an anvil upon which the material is placed, the balanced beam having a fixed state and a movable state, a load assembly for applying a static load to the material when the balanced beam is in a movable state and inducing an initial static strain on the material when the beam is in a fixed state, a hammer opposite the anvil for applying a dynamic strain to the material, a first sensor which senses the dynamic strain applied to the material by the hammer when the balanced beam is in the fixed state, a load cell which detects the force response of the material to the initial static strain and the dynamic strain when the balanced beam is in the fixed state, and a second sensor which senses permanent dimensional changes in the material when the balanced beam is in the movable state.
