Thermal and dynamic mechanical analysis of cross-linked poly(esterurethanes)
PublicationW pracy przedstawiono wyniki badań termograwimetrycznych oraz termomechanicznych usieciowanch za pomocą styrenu i metakrylanu metylu poli(estrouretanów). Uzyskane wyniki pozwoliły stwierdzić, że stabilność termiczna poli(estrouretanów) jest wystarczająca do wielu zastosowań technicznych. Przeprowadzone analizy wykazały również, iż polimery sieciowane styrenem wykazują separację fazową.

Application and mechanical properties of aluminium alloys
PublicationThe paper presents a short survey of the application and mechanical properties of aluminium alloys. This area of scientific research is still developing, the authors restricted it to about 30 papers. Numerical simulations of the aluminium bracket are also investigated. The authors propose a solution to increase the load capacity of aluminium brackets with application of the additional cover plates. This study is proposed as an...

Mechanical Properties of Human Stomach Tissue
PublicationThe dataset entitled Determination of mechanical properties of human stomach tissues subjected to uniaxial stretching contains: the length of the sample as a function of the corresponding load (tensile force) and the initial values of the average width and average thickness of the sample. All tests were conducted in a self-developed tensile test machine: PG TissueTester. The dataset allows the coefficients of various models of...

Mechanical Properties of Aluminium Bracket Strengthening
PublicationThe aim of the research is laboratory investigation of aluminium brackets employed to fasten lightweight curtain walls to building facilities. Tensile loads perpendicular to end plates (vertical) were applied here. The author focused on the solutions intended to increase the load-carrying capacity of aluminium brackets applying the plain washer form A (DIN 125; ISO 7089), plain washer with an outer diameter about 3d (DIN 9021;...

Multibody and electromechanical modelling in dynamic balancing of mechanisms for mechanical and electromechanical systems
PublicationPraca prezentuje zagadnienia wspólnego modelowania układu wieloczłonowego i napędu elektrycznego oraz problemy wyrównoważania mechanizmów. Analizowanym układem mechanicznym jest płaski czworobok przegubowy. Analizowany mechanizm zamodelowano jako układ wieloczłonowy z zamkniętymi wielobokami ciał. Do wymuszenia ruchu układu wykorzystano model silnika prądu stałego. Zbadano oddziaływania pomiędzy płytą mocującą czworoboku i otoczeniem....

Experimental determination of basic mechanical properties of elastomeric polymer
PublicationThere are a lot of different methods of repairing and reinforcing damaged structures, but when it comes to historical buildings and other cultural heritage objects, it is as much about mechanical safety as the aesthetical aspects. Recently, a new and innovative method of repairing damaged structures by filling the cracks with a specially prepared polymer mass has been proposed. This new and innovative technique, known as the Flexible...

Novel analysis methods of dynamic properties for vehicle pantographs
PublicationTransmission of electrical energy from a catenary system to traction units must be safe and reliable especially for high speed trains. Modern pantographs have to meet these requirements. Pantographs are subjected to several forces acting on their structural elements. These forces come from pantograph drive, inertia forces, aerodynamic effects, vibration of traction units etc. Modern approach to static and dynamic analysis should...
