NSTAR is one of the most feature-rich programs available, providing you with powerful tools so that you can get true-to-life results. With an extensive array of nonlinear element types -- including evaluation of J-integrals as a viable fracture criterion for linear elastic and elastic-plastic deformations -- NSTAR makes it possible for you to perform analysis of your model under real-life conditions.
With an adaptive automatic stepping method, as well as automatic calculation of the neutral surfaces for composite shells and automatic evaluation of gap-distances for node-to-node compression gaps based on initial configuration, NSTAR makes it easy for you to get accurate results.
NSTAR helps you analyze nonlinear static and dynamic problems with geometric and material nonlinearities. These include large deflection, large strain, elastic-plasticity, creep, thermo-plasticity, and viscoelasticity. You can also study nonlinear contact problems involving surface interactions of 3D models.
You can use NSTAR with the Basic System, or as a stand-alone system with GEOSTAR, COSMOS/M's fast, graphics-driven pre- and postprocessor. NSTAR: cost-effective, fast, reliable. Everything you need to accurately analyze nonlinear static and dynamic problems.
