Veryst has extensive experience selecting and calibrating material models to capture the most important aspects of material behavior for your specific material and conditions during use. Using our custom software, MCalibration®, we can optimize model parameters for nearly any material model available in commercial finite element (FE) codes and under various loading modes. This also includes the use of complex loading modes requiring inverse calibration methods. We have also developed our PolyUMod® library of advanced material models to expand the capabilities of commonly used commercial finite element packages, including Abaqus, ANSYS, COMSOL Multiphysics, LS-DYNA, and MSC.Marc.
In addition, engineering products experience multiaxial loading at many different strain rates and temperatures. Veryst recommends validating calibrated material models using a separate set of experiments designed to match the loading environment. Such validation test programs are increasingly emphasized by regulatory bodies such as the FDA. Veryst offers multiple validation tests to fit your problem best and can also design custom tests and fixtures for your application. Results from tests are compared to simulations using your calibrated material model in order to validate its predictive capability for your application.
