After using Hooke's Law and assuming that Poisson's ratio and Young's modulus are constant, the stress in the frozen layer is given by [sigma] (z, t) = E/1 - v[[epsilon](t) - [beta] (T (z, t) - [T.
k] is indentation hardness, R is the radius of the hemispherical indenter, P is the force on the indenter, h is the depth on indentation, E is the elastic modulus, and u is Poisson's ratio (usually approximated as 0.
Sigma is also focused on improving its materials data for more accurate shrinkage or warpage simulation by using Poisson's Ratio to calculate data that has not be been directly measured.
