The diagrams opposite show stress-strain curves for a linear elastic material such as a metal (top) and a non-linear elastic material such as rubber (bottom). If these materials are taken to some ...

When a material experiences an applied uniaxial tensile stress, s, it displays a strain response, e. In the initial stage of strain, the response is linear in the stress and may be described by ...

The elastic limit of a material is the furthest point it can ... or directly proportional, to being non-linear. Non-linear extension occurs more in some materials than others.

Materials like clay or putty usually show non-linear extension. Linear extension and elastic deformation can be seen below the elastic limit.
