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.

Computerized deformation analyzer

According to one embodiment of the invention, a method for modeling a feature associated with a deformed material is provided. The method includes generating a first mesh having a model of a feature and a second mesh. A normal distance between a point on the model of the feature and the surface of the first mesh is measured. A location of the surface point of the first mesh that is used to measure the normal distance is determined. The determined location is used to locate the same surface point on the second mesh. A new location for a new point corresponding to the point on the model of the feature associated with the first mesh is determined. The new location is located at the distance as the determined normal distance, but along a normal vector that intersects the same surface point on the second mesh.
