Strain-softening
WebStrain hardening is a natural consequence of most working and forming operation aluminum and its alloys. In pure aluminum and the non-heat-treatable aluminum-manganese and aluminum-magnesium alloys, strain hardening increases the strengths achieved through solid solution and dispersion hardening. ... Tempers for age-softening aluminum … Web1 Jan 1993 · Special attention is paid to the descending part of the stress-strain curve, which is known to be very steep for high-strength concrete. Addition of steel fibers has a beneficial effect on the strain-softening behavior and significantly increases the toughness, as measured by the area under the stress-strain curve.

WebThe stress-strain curve can be defined beyond the ultimate stress, into the strain-softening regime. Hardening data are given in terms of an inelastic strain, ε ~ c i n , instead of plastic strain, ε ~ c p l .
WebOpenSees Strain Softening Model. A three-dimensional (3D) incremental plasticity constitutive model is developed for simulating the strain softening behavior of soil materials. The constitutive model extends an existing multi-yield surface (MYS) plasticity formulation with a new strain softening logic. *Qiu, Z. and Elgamal, A., 2024.
WebMany soils demonstrate strain-softening behav-ior, as illustrated by Curve A in Figure 12-3. Any of several mechanisms may be used to explain the strength decrease, but it is …
WebOther nonlinear mechanical behavior includes Mullins effect (stress softening under large-strain deformation) and the Payne effect (strain-dependent dynamic modulus within small strain). The Payne effect refers to the observation that with the increase of deformation, the stiffness decreases.
