Ultimate Stress Point: The highest amount of stress on the stress-strain curve, after which necking starts. It’s also important to note that while this is the highest on the graph, the actual highest point happens right when the material breaks. Fracture or Breaking Point: As its name sa...
The stress-strain relationship deviates from Hooke’s law. The strain increases at a faster rate than stress which manifests itself as a mild flattening of the curve in the stress and strain graph. This is the part of the graph where the first curve starts but has not yet taken a turn ...
Only a qualtitative picture of the stress-strain relations during necking can be given.When the loads on the testbar are directly transmitted by a liquid, the uniform strains at necking are constants, which are different, however, for axial and radial necking. The stress-strain relations during...
The stress-strain graph provides engineers and designers a graphical measure of the strength and elasticity of a material. It allows them to predict the behavior of materials used in a given application. To draw the graph, the material must first undergo a tensile test. A tensile test is the...

The region of the stress-strain graph in which deformation is temporary (temporary deformation). plastic regions: 塑性区 If a material is forced beyond the elastic region, it experiences plastic deformation (permanent deformation). Necking:缩颈 现象 The reduction in diameter that occurs as...
The relationship between stress and strain can be plotted on a graph, making a stress–strain curve to form a stress–strain graph (Fig. 2.1.2h). Sign in to download full-size image Fig. 2.1.2h. Ratios of stress to strain on testing can form plots on a graph that demonstrate the ...
On a stress–strain graph, the line of the slope of the curve represents the Young’s modulus of the material, with the shaded area in Fig. 2.2.4a representing the elastic energy stored in the material per unit volume of material. In this range, most of the energy used to load the ...
