The tested specimens were subjected to various variants of heat treatment. The tests were performed at the fatigue test stand MZGS-100 under loading frequency 28.4 Hz. The study was conducted for a constant amplitude of moment Ma = 11.2 Nm and different values of stress ratio R = 1 and 0. Adam NIESONY Professor Professor Opole University The results of fatigue tests of samples made of S355JR steel under random tension-compression with nonzero mean stress are presented. The procedure of experimental research is described.

Both the pipe and the plate were made of S355JR steel. Starting from already known fatigue endurance curves obtained for the same specimens under pure bending and pure torsion, a first series of tests was conducted, in which specimens were loaded in bending for a given fraction of the estimated life and then in torsion until failure. Estimation of the Onset of Crack Growth in Ductile Oct 18, 2018 · The mechanical properties of the S355JR (1.0045) steel under different heat treatments tested in the research programs are listed in Table 1. Another symbol of this steel is 18G2A according to Polish standards, and A678Gr.A according to USA standards. Experimental Investigation of Aluminum Alloy and Steel May 03, 2018 · Buckling restrained braces (BRBs) display balanced hysteretic behavior under reversed cyclic tension and compression forces and dissipate a significant amount of seismic energy during credible earthquakes. This paper reports on an experimental investigation of newly developed BRBs with different core materials (steel and aluminum alloy) and end connection details. A total of four full-scale

Nov 16, 2018 · In the present study, the LSP effect on fatigue life of austenitic stainless steels was investigated by changing the laser parameters. The tested material was austenitic stainless steel 08CH18N10T. The influence of LSP treatment on the fatigue life was examined through the three-point bend fatigue test. Influence of the mean stress on fatigue life of 10HNAP The aim of this paper is to elaborate on the energy model including the influence of the loading mean value and its verification in fatigue tests of 10HNAP steel. The influence of the mean value Materials Free Full-Text Estimation of the Onset of The mechanical properties of the S355JR (1.0045) steel under different heat treatments tested in the research programs are listed in Table 1. Another symbol of this steel is 18G2A according to Polish standards, and A678Gr.A according to USA standards.
