摘要
A computer simulation system is configured to display to a user a graphical user interface to allow the user to import experimental test data, identify a material model that includes one or more parameters to be calibrated during a material model calibration process, perform an iterative optimization process to calibrate the material model, the iterative optimization process uses an optimization algorithm that enforces a constraint based on Drucker's stability criterion across one or more predetermined strain ranges to generate a calibrated material model, assign the calibrated material model to a component of a simulation model based on input from the user, a real-world equivalent of the component being made of the physical material, and perform a simulation that includes the component, the simulation using the stable material model and stable set of parameters to simulate response of the real-world equivalent during the simulation.
