Mechanics of Materials

Mechanics of Materials

The research within Mechanics of Materials at the section ranges from fracture mechanics and fatigue over advanced material models to micro-mechanical studies of complex material systems. Focus is on non-linear material behavior in the context of plasticity, visco-plasticity, anisotropy, ductile fracture and damage mechanics. The fundamental basis for most of the research efforts within the theme of Materials Mechanics is non-linear continuum mechanics and a strong effort has been directed toward micron scale metal plasticity, where higher order continuum mechanics is used to develop theories that describe non-trivial size-effects and micro-scale interface phenomena.

Materials ranging from single crystal metals over polymers and laminates to advanced composite systems, both metallic and non-metallic are investigated. Multi-scale modeling and homogenization methods are developed in order to establish macroscopic properties from micro-structural characteristics. In collaboration with materials scientists at the Materials and Surface Engineering Section theories for micro-structural evolution following plastic deformation of metals are pursued.

The long standing and strong tradition of research in ductile fracture at the section is continued and strengthened as young faculty members successfully have been able to reproduce complicated fracture modes that were hitherto believed to be anomalous. In this context the expertise in ductile fracture modeling is well used to seek qualitative as well as quantitative understanding of the variety of ductile fractures.

A significant effort within the research theme is directed toward light weight structures. Experimental and theoretical research of debond propagation mechanisms in sandwich structures has been extended to also include areas such as advanced hybrid-testing of components, joining technologies, mechanical material characterization, high-speed testing and characterization and fire exposure and protection. Many of the research activities within light weight structures are based on the test facilities in DTU Structural Lab.

Large grants, secured in collaboration with DTU Civil Engineering and DTU Wind Energy, have resulted in state of the art experimental facilities that have opened up for new international collaborations. Much of the research is carried out with strong international research partners as well as industry both in Denmark and abroad.
