Material Constitutive Modeling in Geomechanics

Visualization of Constitutive Models in Geomechanics

This project develops a novel interactive visualization learning and development software tool for material constitutive relations (VizCoRe) used in a wide range of engineering applications. Constitutive relations have been developed to mathematically describe the stress-strain-strength behavior of engineering materials such as metals, plastics, concrete and soils.
