Experimental method of defining biaxial fatigue properties of elastic-plastic construction materials. Part 2 – Experimental research

The paper is concerned with the authors' own method of defining biaxial fatigue properties of elastic-plastic construction materials, for which a theoretical basis was formulated before(Cichański and Sempruch,2005). In the present paper, results of experimental investigations (divided into preliminary and main research) appropriate for the proposed method are described. In the preliminary research phase, an experimental verification of major assumptions and numerical verification of conditions on preparation of test specimens were carried out. During the main research phase, model parameters of plastic and fatigue properties were described and the evaluation of the proposed model (Cichański and Sempruch, 2005) was done.
