Streszczenie:

This paper presents the dynamic analysis of clip-on extensometer–specimen structure subjected to uniaxial tensile tests. The dynamic behavior of such structure is influenced by vibrations that can be caused by external factors, such as vibrations carried by the tensile test machine, “cold-welding” effect (typically at ultra-low temperatures) or internal factors arising from the plastic instability of testing materials. The Portevin–Le Chatelier effect (PLC), discontinuous plastic flow phenomenon (DPF) or Lűders band propagation effect are the most prominent modes of plastic deformations, that are characterized by an oscillatory behavior (plastic instability). Both factors are included in our analysis.
