Large strain viscoelastic constitutive models

International Journal of Solids and Structures, 2001
New material (Lagrangean) and spatial formulations for large strain isothermal viscoelacticity, as extention of the well known generalized linear Maxwell model, are proposed. Both formulations are using the multiplicative decomposition of the isochoric component of the deformation gradient into elastic and viscous components [see \textit{R. W.

A novel fluidic strain sensor for large strain measurement

Sensors and Actuators A: Physical, 2008
Abstract A novel fluidic strain sensor is proposed with the use of a mixture of glycerin with aqueous sodium chloride encapsulated within an elastomer as a mean for piezoresistive large strain measurement. Electrochemical impedance spectroscopy (EIS) is conducted for strain response measurement and equivalent circuit analysis is applied for ...

Large Strain, High Strain Rate Testing of Copper

Journal of Engineering Materials and Technology, 1980
This paper describes the development of a high-speed torsional testing machine and results obtained on the strain-rate dependent strength of copper at large shear strains. Test techniques and data obtained are intended to be useful in applications such as ballistics and machining.

Material Constitutive Law for Large Strains and Strain Rates

Journal of Engineering Mechanics, 2000
This note comments on a strain rate pattern found in tensile tests. This strain rate pattern readily suggests that the Cowper-Symonds equation relating the static and dynamic flow stresses with the strain rate is not valid for a broad range of strains unless its coefficients change.

Strain hardening at large strains in aluminum alloys

The strain hardening properties of high purity Al, commercial purity Al, Al-Mn, Al-Mg and Al-Cu alloys have been investigated at large strains in the temperature range 77-473K. Torsion of short thin walled cylinders was chosen as the deformation method because large strains can be achieved without such problems as friction and redundant work.

Strain-Rate Effects in Metals at Large Shear Strains

1983
Many problems in ballistics involve very large shearing deformation occurring at high deformation rates. Such problems include, for instance, explosive formation of shaped charge jets or selfforming fragments and the defeat of thick targets by long rod penetration.

On the applicability of generalized strain measures in large strain plasticity

2006
In the present paper two thermodynamically consistent large strain plasticity models are examined and compared in finite simple shear. The first model (A) is based on the multiplicative decomposition of the deformation gradient, while the second one (B) on the additive decomposition of generalized strain measures.
