Nils Koppels Allé, DTU
DK-2800 Kgs. Lyngby
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
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
