My research helps to make structures safer, more efficient, and more resilient.
Professor Harm Askes
Harm's research interests are concerned with modelling the behaviour of engineering structures and materials. He develops simulation tools to emulate this behaviour, allowing predictions that would be impossible through physical testing. This helps in making structures safer, more efficient, and more resilient.
His two main themes are:
- Critical time step estimates for use in explicit time integrators.
- Penalty methods in dynamics to enforce constraint conditions.
Mechanics of Materials:
- Wave propagation through micro-structured materials.
- Gradient-enriched continuum theories.
In his free time, Harm enjoys reading comics and modern European history, cooking and running. He has published one novel (in Dutch) and has been a life-long fan of AFC Ajax 1981-1987, 1993-2004 and 2009-2014
