I am using one film mateial (Polyester Polyurethane) for some purpose. I have got data sheet from the manufacturer with following details: Durometer 90Shore A D 2240 Specific Gravity 1.19 D792 Elongation @ Break Elast 515% D 412 Tensile Str. @ Break Elast 5,400 psi D 412 100% modulus 1500 psi D 412 300% modulus 2950 psi D 412 Here D.... is the ASTM test method. I have to determine Young modulus for this material, I don't have details of ASTM test method. I have uploaded PDF file of material spec too. Can anyone help me here?
