Figure 4.1: An elastic-perfectly plastic material. (a) Uniaxial stress-strain relation; (b) geometric representation of yield surface and criterion of loading and unloading. Perfectly plastic ...

The study of elastic strain dates from the one-dimensional Hooke's law (1676), and from the general three-dimensional form of Hooke's Law, which was formulated by Cauche almost 200 years later (1839).

Figure 8.1: Bauschinger effect, i.e., an unequal raising of the yield value or actual lowering when the yield stress is reversed. In developing suitable constitutive equations for plastic materials, ...

The elastic modulus relates the applied stress to the strain it produces. In a material that obeys Hooke's Law, the initial uniaxial elastic response is linear with stress and strain coupled through ...

It is also necessary to know the limit of elastic behavior when designing a component that will be exposed to high stress during use. The stress-strain diagram opposite shows the response of a ...
