Metals: TMF (Thermo-mechanical fatigue) of metals is a truly material-centric problem, especially in high value components such as turbine blades, engine cylinder heads or exhaust manifolds. Our experience spans
- Data collection from an array of tensile, creep, LCF/HCF, TMF and SRP tests, and calibration of material parameters to a suitable mathematical model;
- Framework to develop new and/or modify existing material model to capture the observed physical behavior, and deploy suitable numerical algorithms to solve the mathematical problems; and
- Reliable post-processing computations for life time predictions.
Polymers: This class of materials, which are widely used in engineering applications, exhibit complex time-dependent nonlinear response including hyper-visco-elasticity, hysteresis, to name a few. A thorough understanding of the behavior of these materials can facilitate reliable design, analysis, production and deployment of a component that is subject a wide strain-range over a long time duration.
At NW Numerics, we not only do our own testing of polymeric materials, but we have also developed and deployed reliable simulation solutions at enterprise customer sites, thanks to a modern modular material simulation framework that captures several aspects of the physical mechanisms exhibited by polymers.
