My advanced course on Modeling of Localized Inelastic Deformation (LID 2024) will take place in Prague on 2-6 September 2024. |
|
I graduated from the Czech Technical University in Prague in 1985, and then I accepted a teaching position at the Department of Mechanics of the Faculty of Civil Engineering. I was also taking math courses at Charles University. |
 |
In 1991 I started my graduate studies at Northwestern University under the supervision of Prof. Zdenek P. Bazant. My dissertation dealt with various aspects of quasibrittle fracture in concrete, rock, and ice. After graduation I went back to Prague for one year. |
 |
From 1994 till 2004 I
worked as a research engineer at the Swiss
Federal
Institute of Technology at Lausanne (EPFL) in the Laboratory of Structural and
Continuum Mechanics (LSC). I supervized two doctoral students,
Simon Rolshoven and Peter
Grassl. |
| |
Since August 2004 I have been working as a professor in the Department of Mechanics of the Czech Technical University in Prague. Currently I supervise or co-supervise several doctoral students: Michal Smejkal, Lorenzo Baldi (University of Florence), Florian Marconi (ENS Cachan, Paris-Saclay), Marianna Puccia (University of Palermo), Evzen Korec (Imperial College). I collaborate with my colleague Bořek Patzák on the development of OOFEM, an object-oriented finite element package. |
Teaching activities:
|
I have developed a short advanced
course that I taught at various European
universities. Since 2004, this course has been given every year in
September in Prague. The next edition is going to take place on 2-6
September
2024. At the Czech Technical University in Prague, I regularly teach undergraduate courses on Strength of Materials, Structural Mechanics III and Deformation and Failure of Materials, and graduate courses on Universal Principles of Mechanics and Structural Analysis of Historical Constructions. I also teach a doctoral course on Tensor Mechanics and contribute to Scientific Writing and Publishing in English. |
 |
In 2001 I finished a book
on Inelastic Analysis of
Structures, co-authored by Prof. Zdenek P. Bazant
and
published by John Wiley and Sons,
Chichester. |
 |
In 2017 I finished another book
on Creep and Hygrothermal Effects in Concrete
Structures, co-authored by Prof. Zdenek P. Bazant
and
published in January 2018 by Springer,
Dordrecht. |
 |
My research activities
focus on numerical models for fracture and damage of concrete,
