PhD Delft University of Technology

Profile

Dr. Weerheijm studied civil engineering at the Technical University of Delft. In 1981 he joined TNO Defence Security and Safety ( the former Prins Maurits Laboratory) and gained experience in explosion effects, soil and structural dynamics. In 1992 he finished his PhD study on concrete material behaviour at high loading rates. After being the manager of the research group Explosion Prevention and Protection for 10 years, in 2003 he rejoined the TU Delft for two days a week. He is responsible for the research field Impact Dynamics of Structures and Materials.

Dr. Weerheijm was in charge of the TNO contribution to the governmental research of the firework disaster in Enschede 2000. At TNO he is senior research scientist and responsible for the research on protective materials under extreme conditions. He also is programme manager for explosion safety in tunnels and the resilience of urban infrastructure.

Research interests

Material dynamics, heterogeneous materials; rate effects in concrete; fracture mechanics; structural dynamics; explosion effects and wave phenomena.
