Material-centric modeling and simulation system
NWN Z-mat has been built around sophisticated mathematical material models, numerical algorithms, and tools such as stand-alone simulator and optimization program, in a modern software framework. A vast majority of the material models have been experimentally verified and validated in our own lab facilities. Many of these material models are being used in day-to-day design and simulation of high value components by enterprise customers.
Z-mat Library: Key aspects of material models include frameworks that support
- Elastic, visco-elastic, visco-plastic, creep, and damage models suitable for small and large strain computations;
- Many combinations of the above models, including multi-potential mechanisms; and
- A wide variety of fail-safe algorithms with controls.
See this data sheet for more details.
Z-sim: GUI or input file driven material simulator for homogeneous deformation at a material point lets you specify either a history of stress or strain components along with a set of controls, in order to get response of any supported material for uniaxial, biaxial, simple shear or other possible deformation states.
Z-opt: Works with Z-sim or full blown boundary value problem that is FEA simulation to optimize the material coefficients from a given set of test data.
Z-post: Examines FE simulations effectively to produce valuable insight. Some of our life time models are also calibrated against test data from our lab facility.
