dear all, as a newbie in solid mechanics modelling, i always come across these few terms, Cauchy-Green strain tensor Green Lagrange strain tensor isochoric Cauchy green strain tensor. Consider a cubic, when we move the top face, while fixing the bottom face, we will able to see the strain occur, then it generate stress. May i know is this fall in which type of tensor? is it difference in terms of vector direction or plane motion? i am struggling to explain it in to myself.
