# Approximately how many types of stress are there?

Approximately how many types of stress are known/defined? Ex. Piola stress, Cauchy stress ...

For example 2-PK stress works nicely with Green strain, which is a convenient way to define the behavior of a body which has "small" elastic deformations superimposed on arbitrary large rigid body motions - in particular, large rigid body rotations, where approximations like $\sin \theta \approx \theta$ are not appropriate.
