Department of Technical Mechanics provides courses concerned with analytic and numerical methods in engineering. Except teaching, the staff of the department held extensive research focused on the development of numerical and analytical methods for analysis of auxetics, anisotropic and smart materials under the action of mechanical, thermal, electric and magnetic loading. Novel computational approaches are developed.

Department of Technical Mechanics provide Bachelor am Master programs in Applied Mathematics (Speciality 113 – Applied Mathematics) with specialization in Programming and Computational Mechanics. Students are taught state of the art methods of contemporary computational engineering focused on development of computational approaches using parallelization and multiprocessing.
