WebbFor tensile and compressive stress, the slope of the portion of the curve where stress is proportional to strain is referred to as Young’s modulus, and Hooke’s Law applies. Between the proportional limit and the yield point, Hooke’s Law becomes questionable, and strain … Webb23 aug. 2024 · O-A: Proportional limit. Between O to A point, strain is proportional to stress. What that means is the if you put more external force, more strain will occur. In this zone, the part will come back to its original shape if the load is removed. So this area follows the Hookes law that says that the stress is proportional to strain. O-B: Elastic ...

The ratio of stress to strain gives always a similar constant within this limit. This constant is known as Young … talktophillip phillip.com.sg

Stress-strain curve Flashcards Quizlet

WebbBut when engineers say “the stress-strain curve,” they mean a graph that results from a simple tensile test. A material is pulled and a machine measures the changing length and force. ... Proportional Limit is the straight-line portion of the elastic regime. This is often the same as the yield 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 otherwis… Webb11 apr. 2024 · A precise value for the proportional limit is difficult to obtain, particularly when the transition of the stress-strain diagram from a straight line to a curve is gradual. … talktopets.com
