CHALLENGES FOR SIMULATIONS

FEM algorithms and simulations have matured to a state where the biggest hurdle is the lack of material models.

The multi-scale aspects of phase transformation and deformation mechanisms make the modeling of material behavior very complex. Most FEM packages have only simple models implemented in their libraries.

We provide state-of-the-art material models for the production and performance of metallic components.

Safe Light

SafeLight is a library of models for material failure based on stress tri-axiality that can capture the post-buckling behavior, including the element size and thickness dependency.

Phases

Phases is a library of models for predicting the microstructure (grain size, precipitation, phase composition, plastic strain, and damage evolution) during hot/cold forming.

Caliber

GMoP (Generic Modeling Platform) is a material modeling platform that enables quick parameter estimation of material models by calibrating with experiments.

Support

Engineering support integrates our libraries with the client’s existing analysis software to predict material failure and post-buckling behavior accurately.

CALIBRATION & VALIDATION

Sophisticated models need to be calibrated with equally sophisticated measurements.

A carefully planned set of experiments are needed to calibrate the models.

Gleeble™ thermo-mechanical simulator can be used to generate stress-strain curves from room temperature to above 1100°C and strain rates up to 50 per second.
A tensile testing machine equipped with digital speckle photography and digital image correlation can estimate the local strains before the damage.
If the model needs to work at elevated temperatures, dilatometry / calorimetric measurements combined with metallography must be performed.
To validate the models, more complex tests with controlled boundary conditions are performed.
