Effects of strain rate and strain hardening on a cantilever under impact
Proceedings of the Institution of Civil Engineers - Engineering and Computational Mechanics, 2020An investigation is carried out to assess the response of elastic–plastic and ductile circular section cantilevers subjected to blast wave loading. A mathematical equation is formulated for the effects of strain rate and strain hardening for ductile (rigid–plastic) cantilever subjected to impact.

Strain hardening, rate sensitivity, and gradient plasticity
2023Abstract Models of strain hardening and rate sensitivity are described. The classical model of isotropic hardening, applicable to any kind of material symmetry, is discussed, together with the modeling of the elastic-viscoplastic response of isotropic and crystalline materials.

Abnormal strain hardening in nanostructured titanium at high strain rates and large strains
Journal of Materials Science, 2006Commercial purity nanostructured titanium prepared by equal channel angular pressing plus cold rolling (grain size ∼260 nm) exhibits a nonnegligible strain hardening behavior at large compressive strains (>15%) and quasistatic loading conditions. The degree of the strain hardening increases with increasing strain rates and becomes more pronounced at ...

Experimental Mechanics, 2014
This paper is concerned with comparison of the tensile properties of Al1100 thin film in a micro-scale to that of Al1100 sheet in a macro-scale. The material properties of Al1100 film and sheet with a thickness of 96 μm and 1 mm respectively have been investigated at strain rates ranging from 0.001 to 100 s−1. The experiments were conducted with Static

Strain rate hardening: A hidden but critical mechanism for biological composites?
Acta Biomaterialia, 2014Natural materials such as nacre, bone, collagen and spider silk boast unusual combinations of stiffness, strength and toughness. Behind this performance is a staggered microstructure, which consists of stiff and elongated inclusions embedded in a softer and more deformable matrix.

Strain-rate effects on the tensile behavior of strain-hardening cementitious composites
Construction and Building Materials, 2014Abstract This paper investigated the strain-rate effects on the tensile properties of strain-hardening cementitious composite (SHCC) and explored the underlying micromechanical sources responsible for the rate dependence. Experimental studies were carried out to reveal rate dependence in component phases, i.e.

Mechanics of Time-Dependent Materials, 2018
In this paper the influence of increasing loading rates on hardening effects is analyzed for rate-dependent elastoplastic materials. The effects of different loading rates on hardening rules are discussed with regard to the constitutive behavior of strain-hardening materials in elasto/viscoplasticity.

The Influence of Strain Hardening and Strain-Rate Sensitivity on Sheet Metal Forming
Journal of Engineering Materials and Technology, 1977The current understanding of sheet metal stamping processes is discussed in the light of materials’ ability to distribute plastic strains in uniaxial and biaxial deformation. The focus is on the plastic flow properties, namely strain hardening and strain-rate sensitivity.

Journal of the Mechanics and Physics of Solids, 1986
Abstract A n up-to-date approach to the phenomenon of rate sensitivity observed in f.c.c. metals is discussed. It is shown that the rate sensitivity of strain hardening, which so far has been neglected, plays an equal or even dominant role in an estimation of the total rate sensitivity.
