Petr Krysl

Professor, Structural Engineering

Finite element computational modeling techniques for solids and structures, model order reduction in nonlinear mechanics, and computer and engineering simulations in multiphysics problems.

Petr Krysl has made major advances in finite element and meshless discretization methods applied to problems of structural and solid mechanics: mesh generation, thin shell simulations, adaptive nonlinear computations, dynamic crack growth, adaptive mesh refinement, and parallel algorithms. Krysl is currently working on problems of optimal modeling for nonlinear dynamic applications, such as earthquake engineering and design of micromechanical devices, and adaptive finite element modeling for multiphysics problems. His research interests include finite element technology for computational mechanics of solids and structures; mesh generation and CAD/analysis integration; methods for solid and structural dynamics; computational modeling in earthquake engineering; and model order reduction for nonlinear dynamics. Recently, Krysl designed an adaptive finite element mesh refinement technique that is proving to be an important tool for engineering and scientific simulations.

Capsule Bio:

Czech Republic in 1993. Prior to coming to UCSD in 2000, Petr Krysl was a staff scientist at the California Institute of Technology. Krysl is a member of the International Association for Computational Mechanics, the International Society for Grid Generation, the American Society for Engineering Education, and the Society for Industrial and Applied Mathematics, and is a reviewer for many highest-quality journals in the field of structural and computational mechanics, such as the Journal of Structural Engineering ASCE, Computer Methods in Applied Mechanics and Engineering, Communications in Numerical Methods in Engineering, and the International Journal for Numerical Methods in Engineering.
