I've been doing some work with simple Abelian groups and their generators, and I feel like there is a way to classify all of them, is this possible?

Yep. It's been done. Since any subgroup of a abelian group is normal, a simple abelian group must have only {e} and itself as subgroups. Thus the only simple abelian groups are the (cyclic) groups of order p, where p is a prime.
 
Thread 'Derivation of equations of stress tensor transformation'
Hello ! I derived equations of stress tensor 2D transformation. Some details: I have plane ABCD in two cases (see top on the pic) and I know tensor components for case 1 only. Only plane ABCD rotate in two cases (top of the picture) but not coordinate system. Coordinate system rotates only on the bottom of picture. I want to obtain expression that connects tensor for case 1 and tensor for case 2. My attempt: Are these equations correct? Is there more easier expression for stress tensor...
