http://www.ae.iitkgp.ac.in/ebooks/chapter4.html Young's modulus , the Young modulus, or the modulus of elasticity in tension or compression (i.e., negative tension), is a mechanical property that measures the tensile or compressive stiffness of a solid material when the force is applied lengthwise. It quantifies the relationship between tensile/compressive stress (force per unit area) and axial strain (proportional deformation) in the linear elas…
WebDesmopan® and Texin ® grades range in hardness from 60–98 Shore A to 30–75 Shore D. They are characterized by high values for tensile stress and elongation at break, but these properties are only of interest when describing the materials.
