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.
- To validate the models, more complex tests with controlled boundary conditions are performed.
