Proof stress and yielding behaviour

  1. Apr 3, 2009 #1
    Discuss how well the proof stress describes a material’s yielding behaviour. Explain why we use
    proof stress as a measure of yielding.

    This looks like a homework problem or classroom assignment.

    Please explain one's understanding of 'proof stress' and 'yielding'.

    Is one familiar with the elastic range of a material and Young's (elastic) modulus?

    I have the same question as above.

    How does the propf stress describes the yielding behaviour and why do we use the proof stress as a measure of yielding.

    i would be really thankful if someone can give me the answer or some hints. thank you !
