Homework Help: Tensile test Assignment

  1. Dec 30, 2011 #1
    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.
