negative stress = compressive stress ?

Please login with a confirmed email address before reporting spam


Hello,

I have a simple question. When my value of normal stress is negative, is it then a compressive stress in general. So if it is positive, is it then tensile stress?
Or does the minus and plus just mean in which direction the stress vector is pointing?

Thanks and kind regards!

C. Mannal

Hi

what if you try something like this (its V4, check that it's the same in V3.5)

Hi
And here are the view (only that in V4 it's not easy to identify which legend corresponds to which graph, but as the countour is Von Mises and von Mises >0 you should be able to identify it still unambiguously)

Have fun Comsoling
