Abstract

A computer-implemented method includes obtaining a model representing a physical object, accessing a discretized yield surface having a plurality of data points representing a yield surface of one or more materials of the physical object, each data point corresponding to a point in a stress space and associated with a yield surface normal vector precomputed for the discretized yield surface, and calculating a stress at an integration point of the model to simulate the physical object under a load. The method further includes identifying one of the plurality of data points of the discretized yield surface that corresponds to the stress calculated in the stress space, determining plastic deformation is occurring based on the stress calculated and the one data point identified, and adjusting the stress according to a normal vector associated with the one data point identified to simulate plastic deformation of the physical object under the load
