Tubular specimens of mild steel are subjected to tensile prestraining and then aged under compressive stresses along the Bauschinger curve, at various temperatures below 175 掳C. The compressive (reversed) stress imposed on the specimen during aging, called here the aging stress, is employed up to...
Tensile strength is resistance of steel to breaking under tension. When two equal and opposite pulling forces is applied over steel specimen, stress is develop known as tension stress which causes stretching or elongation in specimen, so tensile strength of steel is maximum strength of steel to re...
Once the steel is pulled from its stress point, it splits apart. Tensile Strength of Mild Steel Tensile strength is the maximum amount of stress that any material can withstand when pulled or stretched. Any tensile strength undergoes a test that includes taking samples of a material with a ...
At the yield point, the curve deviates from linearity. This signifies the onset of plastic deformation. The stress required to reach this point is theyield strength. Beyond the yield point, the material enters theplastic deformation zone. Here, the amount of deformation increases significantly with...
The results of investigations of the influence of high strain rates on yield stress of some structural metals are presented. Specimens from mild steel, high strength steel (HRA) and titanium alloy in the form of 2-nm thick sheet blank with regular parallel slits are used for impact compression...
Yield Stress and Flow Stress of Iron and Steel under Dynamic Loading The dynamic tensile tests of pure iron and low carbon steel at a strain rate of 30/sec were performed at room temperature and 78掳C. The results of measurements of the yield and the flow stress were analyzed on the basi...
The effect of strain rate on the post-yield flow of mild steel A brief description is given of a rapid-loading hydraulic test machine which was used in an earlier investigation of delayed yielding under constant stress. A modification to the machine is also described, which makes it possible ...
The yield strength of FRMLs depends on the residual stress in the metal layers, the constituent alloy in the laminate, and the degree of straining of the fibers during the cure process or of the whole laminate after cure. From the rule of mixtures, the fraction of the total load on the...
Since flattened steel sheets often show the unexpectedly lower or higher yield strength than leveled sheets, unceasing efforts have been made to accurately predict the yield strength in pipe-forming industries. In the present investigation, the yield strength of line-pipe or casing-pipe steels was ...
It appears that the drop in stress after the first yield is responsible for the localisation of plastic flow, and that this localisation may in turn be responsible for the macroscopic shear associated With the L眉ders deformation. The existence of this shear influences the pattern of the bands ...
