    Veritas est Scientia 

THERMOMECHANICS - Connecting continuum mechanics and thermodynamics of materials using frame-indifferent constitutive relations restricted by the second law of thermodynamics, and physically and mathematically described using differential geometry (OUR DEFINITION)

IN OTHER WORDS … We’ve never met a contact system we didn’t like.

THE LABORATORY – Makes use of experiments and analytical models for materials in the areas of continuum mechanics to solve real-world engineering problems. Tribological problems related to contact mechanics and dissipative processes are also of special interest.
