Hello, I'm not sure if this is the right place to ask about Continuum Mechanics or if the right place would be the engineering forums, but since Continuum Mechanics is a branch of Classical Mechanics, I thought it might be the place.(adsbygoogle = window.adsbygoogle || []).push({});

My question is about Stress. Why does the stresses on opposite sides of an infinitesimal cube have to be the same? I know about the equilibrium. But what if the continuum is accelerating (for example if it is part of a fluid)? How can you describe the stresses on a point? If usually we use a stress tensor with nine components with respect to three orthogonal interfaces at a point, now this wouldn't be possible since we would have eighteen different stresses at that point.

I can't find any continuum mechanics forums on the internet. If you know of anyone, please tell me and sorry for the amount of questions.

Thanks,

VĂtor Mussa T. Gomes
