Here is what additional definition I found (if you want the WEB site, I will be glad to post it):
There are three main types of stress. If we stretch or compress an object, we are subjecting it to a tensile stress. If an object is subjected to a force along an entire surface, changing its volume, then it is said to be experiencing a bulk stress. Finally, if the force is acting tangentially to the surface, causing it to twist, then we are subjecting it to a shear stress.

I'm just wondering if there's a difference between Druckschwell ....and Zugschwell

I don't really see all that much difference from the question you posted earlier?
