The Department has three Divisions:

• Experimental Mechanics (Prof. Zbigniew L. Kowalewski, Ph.D., Dr habil.)
• Mechanics of Plastic Flow (Prof. Lech Dietrich, Ph.D., Dr habil.)
  
• Technological Laser Applications (Prof. Zygmunt Szymański, Ph.D., Dr habil.)

The Department constitute a part of the Centre of Excellence for Safety-Critical Pressure Systems nominated by the State Committee for Scientific Research and is also nominated by the European Commission as the Centre of Excellence for Laser Processing and Material Advanced Testing "LAPROMAT".

Current Research Activities:

• Experimental investigations of mechanical properties of materials and structural elements under uniaxial and complex stress states, including:
  determination of yield surface and its changes due to different loading history of standard and novel engineering materials including functional materials,
  determination of plastic anisotropy and its variations due to plastic deformation and time,
  creep testing of materials,
  evaluation of the influence of plastic deformation history on creep characteristics of materials,
  evaluation of the effect of strain rate on the mechanical properties of engineering materials,
  mechanical properties of materials under proportional and non-proportional cycle loading,
  testing of fatigue, fracture and damage of materials,
  fracture toughness testing of materials,
  identification of mechanical properties of materials.
• Investigations of phenomena in laser material processing:
  laser welding: process engineering problems, plasma role, keyhole oscillations, optical and acoustic signals emitted during welding,
  laser surface modification: hardening, alloying, corrosion resistance,
  laser forming of metal elements,
  sensing and monitoring; welding, surface modification, forming.
