You should be able to answer these questions without too much difficulty after studying this TLP. If not, then you should go through it again!
Use the interactive Mohr's circle below to help you with this question. Which of these stress states is not the same as the others?
What kind of movement are these tensors - rotation, strain or both? Click on each and check the answer.
The yield stress of an aluminium alloy in uniaxial tension is 320 MPa. The same alloy also yields under the combined stress state:
Is the behaviour of this alloy better described by the von Mises or the Tresca yield criterion?
