Explain stress strain curve
WebThe stress-strain curve contains no higher stress than the ultimate strength. Even though deformations can continue to increase, the stress usually decreases after the ultimate strength has been achieved. It is an intensive property; therefore its value does not depend on the size of the test specimen. WebFeb 12, 2024 · In a stress-strain curve, the area under the curve is often considered a measure of toughness. In the sketch below, Material 2 has higher toughness than Material 1.

In engineering and materials science, a stress–strain curve for a material gives the relationship between stress and strain. It is obtained by gradually applying load to a test coupon and measuring the deformation, from which the stress and strain can be determined (see tensile testing). These curves reveal … See more 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 … See more It is possible to distinguish some common characteristics among the stress–strain curves of various groups of materials and, on this basis, to divide materials into two broad categories; namely, the ductile materials and the brittle materials. Ductile materials See more A schematic diagram for the stress–strain curve of low carbon steel at room temperature is shown in figure 1.
