Department of Numerical Methods in Materials Engineering

The scientific and research activities of the Department are focused on the use of advanced mathematical-physical, numerical, statistical methods, data mining techniques, as well as the design and development of simulation and database systems. To this end, a range of programming environments (Delphi, C++ Builder, Visual Studio .NET) and database systems (InterBase, MySQL, MS SQL, Access) are utilized in the field of materials engineering.

The department specializes primarily in modeling and optimizing surface and thermochemical treatment processes, including the development of:

• models and algorithms for multi-stage carburizing processes and prediction of low-pressure carbonitriding in variable-temperature and repair processes,

• neural and heuristic models for determining optimal parameters of vacuum carburizing based on target post-treatment layer properties,

• algorithms for quenching steel components with carburized layers in high-pressure gas atmospheres,

• physical models and functional solutions for multi-segment low-pressure nitriding with a "boost–diffusion" process structure,

• numerical models of residual stresses in the surface layer after various surface and thermochemical treatments,

• numerical superposition of stresses and the synergistic effects of advanced mechanical and thermochemical treatments, including external load conditions,

• stress and distortion control algorithms for high-performance vacuum carburizing systems,

• high-speed and dynamic analyses of phenomena occurring during plastic deformation processes.

The Department of Numerical Methods in Materials Engineering collaborates with companies such as SECO/WARWICK SA, Hart-Tech Sp. z o.o., Bionanopark Łódź, Alumetal-Technik Sp. z o.o. Sp.k, carrying out POIR-funded projects and implementation research related to the commercialization of developed solutions. The department’s innovations have received numerous awards and distinctions at international invention and innovation fairs. Additionally, educational computer programs developed by the department serve as teaching aids in the area of heat and thermochemical treatment at nine Polish universities.
