Gradient of stress strain graph

WebIt is the level of stress corresponding to the yield point and is referred to as the yield strength of the material. It is generally difficult to determine the exact yielding point. Key takeaways: Yield strength, Stress-strain curve, Proportional limit, Elastic limit, Yield point, Ultimate stress point, Necking, Fracture point. Generally speaking, curves representing the relationship between stress and strain in any form of deformation can be regarded as stress–strain curves. The stress and strain can be normal, shear, or mixture, and can also can be uniaxial, biaxial, or multiaxial, even change with time. The form of deformation can be compression, stretching, torsion, rotation, and so on. If not mentioned otherwi…
