ABSTRACT:
According to one embodiment of the invention, a method for determining deformation of a surface of a material is provided. The method includes receiving, at a computer, an elastic deformation range and a plastic deformation range of the material. The method also includes modeling a region of the material with a mesh. The mesh includes a plurality of elements. The method also includes 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 results from a set of modeled boundary conditions. The finite element analysis includes recurrently approximating the modulus of elasticity for each element according to the elastic deformation range and the plastic deformation range. The act of approximating is based on a value of strain calculated from a previously calculated element displacement.
