Hi all, I am doing a tensile test assignment and ive hit a brick wall with regards to research just wondered if anyone had any good pointers or books i could look up. I have 3 materials in the tensile test which i have plotted stress/strain graphs for which is all good and well and from the information i've been given i have worked out the UTS of the materials and the youngs modulus from the graphs i've made. Basically the last part is to come to a conclusion as to what they are: material 1: youngs modulus = 300GPa, UTS = 700MPa material 2: youngs = 240GPa, UTS = 425MPa material 3: youngs = 0.45GPa, UTS = 220Pa my guesses so far is that 2 is a form of steel, 3 is a plastic...and number 1? any help would be much appreciated. just looking for pointers to be honest.
