The main research area of the Department of Mechanics & Applied Computer Science is the numerical and experimental strength analysis of miscellaneous type structures and their elements. In the numerical analysis, professional Finite Element Method programmes are used. They enable linear and non-linear numerical analysis of stresses and strains carried out for engineering structures subjected to static or dynamic mechanical loads, stationary or non stationary thermal loads as well as the problems connected with heat transfer and simulation of the fatigue process of a material.

Up to now, in its scientific and expertise activity, has concentrated on the following subjects within the range of numerical and experimental strength analysis:

  • numerical modelling of elements of subcalibre projectiles,
  • simulation of landing gears of military transport aircrafts,
  • modelling of the structure of a helicopter rotor blade made of composites with the possibility of perforations by bullets,
  • numerical simulation of pontoon bridges exploited by the Armed Forces of the Republic of Poland in the context of their possible use by the NATO forces,
  • analysis of multi-disc clutches used in tanks and tracked combat vehicles,
  • modelling of elements of a high-pressure tank engine taking into account thermomechanical processes taking place during its running,
  • simulation of windings of high power transformers,
  • analysis of the structure of pipelines for crude oil and gas transport,
  • determination of residual stresses and simulation of cracking in alumina based ceramics,
  • simulation of gears' running in machine elements for power transmission,
  • investigation of the influence of thermomechanical phenomena on a blade's operation in a turbine,
  • investigation of structural elements' work in aircrafts in conditions of prolonged operation,
  • simulation of the state of high storage store halls structures,
  • investigation of pipeline elements for transport of thermal media in thermal-electric power stations,
  • simulation of structural elements of vehicles behaviour in conditions of accidents and collisions,
  • modelling of riveted structural joints,
  • rheological investigation of laminated materials and composites,
  • creep tests of valve steel,
  • dynamic tension, compression and bending tests of plates made of polymer composites,
  • investigation of residual stresses in the shaft top lining in a coal-mine by the "Vishay" and interferometric-holographic methods,
  • static and dynamic tests on specimens and structural elements made of the Al-Mg alloy,
  • in situ investigation of mechanical properties of rocks around excavations using the hole penetrator and the tunnel rock destruction methods,
  • determination of the state of strain in structural elements by the: electric resistance strain gage, photoelastic and holographic methods.


The team of the Department of Mechanics & Applied Computer Science are ready to co-operate with partners from Poland and from abroad in the following areas:
  • Participation in design of new structures,
  • Improvement of characteristics and strength of already-exploited structures,
  • Assessment of the technical state of structures or their elements after a prolonged process of exploitation,
  • Sensitivity analysis and safety improvement from the point of view of strength of objects and structures exposed to possible activities of terrorist groups.
