Since 1994 professor of Materials Mechanics. Before that research professor for 5 years. Was also appointed visiting professor at Brown University, RI, USA, for a 5 year period. Research on many aspects of Nonlinear Mechanics, often in collaboration with colleagues at Brown University, Harvard University, Delft Technical University, etc.

Stability of plate and shell structures - Post buckling behaviour, imperfection sensitivity, plastic buckling, energy absorbtion in collisions, structural collapse.

Mechanics of materials - Mainly nonlinear material models, plasticity, viscoplasticity, high temperature creep, damage mechanics. Applications of these material models for structural components. Localization of plastic flow. Fully nonlinear dynamics.

Fracture mechanics - Cracks and crack growth in structural metals, and in metal ceramic systems. Creep crack growth at high temperatures. Fatigue. Nonlinear fracture mechanisms.

Micromechanics - Nonlinear studies of micro effects such as void growth to coalescence, micro cracking, grain boundary sliding. Effects of micro mechanisms on macroscopic material behaviour and vice versa.
