The Transition from Strain Softening to Strain Hardening in Metallic Glasses [PDF]
NanomaterialsDespite their excellent mechanical properties, metallic glasses (MGs) are significantly hindered by poor plasticity and toughness, which are essential for structural applications.

Evaluation of input geological parameters and tunnel strain for strain-softening rock mass based on GSI [PDF]
Scientific Reports, 2022 The regression analysis method is being widely adopted to analyse the tunnel strain, most of which ignore the strain-softening effect of the rock mass and fail to consider the influence of support pressure, initial stress state, and rock mass strength ...

Strain-Softening Analyses of a Circular Bore under the Influence of Axial Stress
Applied Sciences, 2021 Strain-softening analyses were performed around a circular bore in a Mohr–Coulomb rock mass subjected to a hydrostatic stress field in cross section and out-of-plane stress along the axis of the bore.

Viscoplasticity for instabilities due to strain softening and strain-rate softening [PDF]
International Journal for Numerical Methods in Engineering, 1997 Three viscoplastic approaches are examined in this paper. First, the overstress viscoplastic models (i.e. the Perzyna model and the Duvaut—Lions model) are outlined. Next, a consistency viscoplastic approach is presented. In the consistency model a rate-dependent yield surface is employed while the standard Kuhn—Tucker conditions for loading and ...

Materials Research Express, 2022 During hot working, alloys may experience three kinds of flow stress behaviors, including strain hardening, strain softening, or steady flow, because of the competition of work hardening and thermal softening. Modelling the flow stress behaviors plays an
