1. A computerized method for determining deformation of a surface of a material, comprising:
receiving, at a computer, an elastic deformation range and a plastic deformation range of the material;
modeling a region of the material with a mesh comprising a plurality of elements;
determining, by performing a finite element analysis on the mesh by the computer, a displacement for at least one point on
each of the elements, the displacement resulting from a set of modeled boundary conditions, the finite element analysis including
recurrently approximating the modulus of elasticity for each element according to the elastic deformation range and the plastic
deformation range based on a value of strain calculated from a previously calculated element displacement.
