Mechanics of solids - Inelastic response | Britannica
Mechanics of solids - Mechanics of solids - Inelastic response: The above mode of expressing [σ] in terms of [S] is valid for solids showing viscoelastic or plastic response as well, except that [S] is then to be regarded not only as a function of the present [EM] and θ but also as dependent on the prior history of both. Assuming that such materials show elastic response to sudden stress ...

Abstract. Laser-driven shock experiments were performed on fcc metals, aluminum and invar, at a range of initial temperatures from approximately 120-800 K to explore the effect of initial temperature on dynamic strength properties at strain rates reaching up to 10 7 s-1.In aluminum, velocimetry data demonstrated an increase of peak stress of the elastic wave, σ E, with initial temperature.

To characterize the rate-dependent failure behavior of the aluminum alloy foams, uniaxial compressive stresses of the foams from low to high strain rates are plotted in Figure 20 (Zhou et al., 2014). Based on the present uniaxial data, the empirical formula can be determined to describe uniaxial compressive strength as function of the strain rates:
