Ali Esmaeili

Visiting Researcher at Material and Computational Mechanics

Ali carried out his doctoral thesis for CHARMEC-project MU32:"Modelling of thermomechanically loaded rail and wheel steels". The main goal of project MU32 was to improve material modelling of the cyclic and viscous behaviour of wheel and rail materials subjected to mechanical and thermal loadings. The project was conducted in close collaboration with project MU28. In MU28 tests will were performed on pearlitic steels at elevated temperatures for uniaxial as well as compression–torsional loadings. The project also interacted with project SD10 where simulations of the contact between brake block and wheel including temperature elevation will were studied employing the developed material model.
