Experimental investigations on the softening and ratcheting behaviors of steel cylindrical shell under cyclic axial loading
In this research, softening and ratcheting behaviors of Ck20 alloy steel cylindrical shells were studied under displacement-control and force-control cyclic axial loading and the behavior of hysteresis curves of specimens was also investigated. Experimental tests were performed by a servo-hydraulic INSTRON 8802 machine. The mechanical properties of specimens were determined according to ASTM E8...
متن کاملFatigue strength of bilayered ceramics under cyclic loading as a function of core veneer thickness ratios.
STATEMENT OF PROBLEM Minimal evidence is available concerning the appropriate thickness of each layer in bilayered ceramic systems. PURPOSE The purpose of this in vitro study was to examine the effect of core-veneer thickness ratios on the fatigue strength of a bonded bilayered ceramic system. MATERIAL AND METHODS Specimens of Ivoclar Porcelain System (IPS) e.max lithium disilicate were fab...

متن کاملNumerical and Experimental Study on Ratcheting Behavior of Steel Cylindrical Shells with/without Cutout Under Cyclic Combined and Axial Loading
Ratcheting behavior of steel 304L cylindrical shell under cyclic combined and axial loading are investigated in this paper, numerically. Cylindrical shells were fixed oblique at angle of 20° and normal with respect to the longitudinal direction of the shell and subjected to force-controlled cycling with non-zero mean force, which causes the accumulation of plastic deformation or ratcheting beha...
متن کاملNumerical and Experimental Study on Ratcheting Behavior of Plates with Circular Cutouts under Cyclic Axial Loading
In this paper, accumulation of plastic deformation of AISI 1045 steel plates with circular cutouts under cyclic axial loading is studied. Loading was applied under force-control conditions. Experimental tests were performed using a Zwick/Roell servo hydraulic machine. Under force-control loading with nonzero mean force, plastic strain was accumulated in continuous cycles called ratcheting. Nume...
