Chareyre proposed the following answer:

They SHOULD NOT give the same result be in in theory or in experiments.
The equality you have in mind is only an approximation and yade prooves it.
Consider a cube 1x1x1. If the deformation is e11, e22, e33, then new
volume is (1+e11)(1+e22)(1+e33)=1+e11+e22+e33+e22e33+e33e11+...
Hence dV/V is NOT e11+e22+e33.
