LAOS: The strain softening/strain hardening paradox
Journal of Rheology, 2014Numerous materials, from biopolymers to filled rubbers, exhibit strain softening at high strain amplitudes during a strain sweep in oscillatory rheology: The modulus decreases with increasing deformation. On the other hand, if the nonlinear elastic response is analyzed within a single oscillation cycle (described by a Lissajous curve), these systems ...

Strain Hardening and Annealing
1996In this chapter we will discuss three main topics: cold working, by which a metal is simultaneously deformed and strengthened; hot working, by which a metal is deformed at high temperatures without strengthening; and annealing, during which the effects of strengthening caused by cold working are eliminated or modified by heat treatment.

The Effect of Strain Hardening in an Annular Slab
Journal of Applied Mechanics, 1953Abstract A procedure is outlined for obtaining the stresses and strains in a circular slab with a cutout, subject to uniform biaxial tension. An arbitrary stress-strain curve in tension is approximated by any number of straight-line segments.

Shock Propagation in a Strain-Hardening Material
Journal of Applied Mechanics, 1969Weak shock theory is used to analyze the propagation of the stress waves which are induced by nonuniform, instantaneous, internal heating of a nonlinearly elastic, semi-infinite solid. The material nonlinearity considered is caused by the increase in bulk modulus which occurs as the hydrodynamic stress component increases.
