Project Description

Materials laboratory needed for ASTM Thermal Stiffness property testing as per ASTM D 1043 Stiffness Properties of Plastics as a Function of Temperature by Means of a Torsion Test of 3 rubber parts. The property measured by this test is the apparent modulus of rigidity, G, sometimes called the apparent shear modulus of elasticity. It is important to note that this property is not the same as the modulus of elasticity, E, measured in tension, flexure, or compression.
