About    Fatigue calculations with MATLAB



I am working at the Opole University of Technology as a scientist and academic teacher. My main field of interest are fatigue of materials. My research work concerns strength of machine parts, durability of machine elements and dynamics of structures. I am, among others co-author of a new method of determining material fatigue constants from deformation tests and author of the multi-axis fatigue life criterion, dedicated to the frequency domain approach.

I am happy to cooperate with Colleagues from industry and deal with the transfer of IP. I have been the supervisor of six doctoral dissertations. In my classroom I am teaching fatigue of materials and practical FEM analyses.
