I need to determine Young's modulus and Poisson's ratio from the elastic stiffnesses for a cubic crystal that is being stressed along the x axis.
It is initially L *w and goes to (L+delta L)*(w - delta w). Where w is along the x axis and L is along the y axis. How do I change stresses and strains along with lengths into elastic stiffnesses?
