DAMTUL

Research focus

- non-linear vibration, chaos and bifurcation theory in application to helicopters and aerospace objects taking into account dynamics properties of new materials;

- theoretical modelling and experimental verification of the behaviour of modern composite materials (ceramic and polymer composites) under mechanical (monotonic, cyclic, impact) loading, fracture mechanics of composite materials;

- research on fatigue strength of materials and helicopter structures;

- dynamics of high speed cutting process materials applied to aeronautic objects;

- dynamics, stability and optimisation of thin-walled structures;

Other information

Department of Applied Mechanics of Technical University of Lublin (DAMTUL) consists of two research groups:

group of classical mechanics carries out research encompassing theoretical and applied dynamics of mechanical systems, non-linear vibration, chaos and bifurcation theory, non-linear dynamics in high speed cutting process, cars and helicopters and aerospace object dynamics;

group of material strength conducts research on theoretical modelling and experimental verification of the behaviour of modern composite materials (ceramic and polymer composites) under mechanical (monotonic, cyclic, impact) loading, fracture mechanics of composite materials, fatigue strength of materials and structures, stability and optimisation of thin-walled and sandwich type construction;

Main directions of DAMTUL investigations are strongly connected with the cooperation with industry and with national and foreign universities and European Union. DAMTUL co-operates with many partners from United Kingdom, Germany, France, Czech, Hungary, Russia, Italy, Belgium, Greece, Ireland, Brazil and USA and has established permanent contacts with the local industry. The most important is co-operation with Helicopter Factory PZL - Świdnik S.A. Joint research is concentrated on fatigue strength of main parts of helicopter, rotor dynamics, applications of new materials in helicopters designing and analysis of their static and dynamic properties in micro and macro scales. Some design engineers employed at that factory, have been graduated from DAMTUL and a few make Ph.D. thesis at Technical University of Lublin. The book "Introduction to Helicopters Designing" by K.Szabelski, B.Jancelewicz, W.Łucjanek, W.K.Ł., Warszawa 1995, was published as a result of this intensive co-operation. The project entitled "The Main Rotor with High Strength Properties for Helicopter PZL W-3 SOKOL" is performed for Helicopter Factory PZL - Świdnik S.A

DAMTUL also co-operated with Lublin Cars Factory on testing of fatigue strength of elements of van "Lublin", dynamics of car suspensions and vibrations isolation generated by engine. In years 1981-1986, a special state grant "Research of Mechanical Properties of Optical Fibres and Cables" was carried out. In this grant new experimental methods for investigations of optical fibres properties were developed and eight experimental devices were constructed. This research took a main prize founded by Polish Government. In years 1995-1997, Department made a theoretical and experimental stress analysis of deep spherical tanks of ammonia for Nitric Works in Puławy (near Lublin). Additional cooperation is connected with "Kraśnik Rolling Bearing Factory" and "Lublin Factory of Agriculture Machines".

Competence and reliability of DAMTUL staff establish good bases for effective and sufficient work, when new possibilities occur.
