End Effects in Prestrained Plates Under Compression

Journal of Applied Mechanics, 2004
The decay of end perturbations imposed on a rectangular plate subjected to compression is investigated in the context of plane-strain incremental finite elasticity. A separation of variables in the eigenfunction formulation is used for the perturbed field within the plate.

Dynamic deformation of shock prestrained copper

Materials Science and Engineering: A, 1991
Abstract Measurements of yield stress and strain hardening behavior at strain rates in the range 10 −3 –10 4 s −1 are reported for copper that has been previously shock deformed at a shock pressure of 10 GPa. Characterization of the mechanical properties and microstructure, using transmission electron microscopy, showed that the hardening induced by

A strain-gradient theory for prestrained laminates

International Journal of Solids and Structures, 1973
Abstract A simple strain-gradient theory is developed for prestrained laminated materials consisting of thin, stiff reinforcing sheets embedded between thick, soft layers of a matrix material. The theory is used to investigate three types of instability that may occur in massive bodies: global, edge and internal buckling. The predictions for internal

On the viscoelastic properties of prestrained rubber

ZAMP Zeitschrift f�r angewandte Mathematik und Physik, 1983
The material behaviour of rubber is investigated for a special type of deformations namely small amplitude vibrations superposed on finite static prestrain. By restricting the magnitude of the prestrain it is possible to derive a simplified constitutive equation which can be used to solve simple boundary value problems.

Void Coalescence With and Without Prestrain History

International Journal of Damage Mechanics, 2009
In this study, void coalescence with and without a plastic prestrain history is studied using stress-controlled axisymmetric unit cell models. In addition to spherical voids, both oblate and prolate voids are considered. In the case with prestrain history a uniaxial prestrain up to 10% was applied and the material is thereafter subjected to loadings ...

Subultimate Prestrain and Aging in Mild Steel

Journal of Basic Engineering, 1965
Room-temperature tensile straining of mild steel followed by aging at 350 F causes return of the upper yield and a raising of the stress-strain curve. Tensile tests on a special rimmed steel of low Mn/C ratio show not only the expected raising of the stress-strain curve, but raising by an additional amount when several small increments of strain are ...

Propagation of axisymmetric longitudinal waves in a finitely prestrained circular cylinder imbedded in a finitely prestrained infinite elastic body

Mechanics of Composite Materials, 2008
Within the framework of a piecewise homogeneous body model and with the use of the three-dimensional linearized theory of elastic waves in initially stressed bodies (TLTEWISB), the propagation of axisymmetric longitudinal waves in a finitely prestrained circular cylinder (fiber) imbedded in a finitely prestrained infinite elastic body (matrix) is ...

Diffusion of incremental loads in prestrained bars

Proceedings of the Royal Society of London. Series A: Mathematical and Physical Sciences, 1992
Abstract Axial diffusion of perturbed fields generated by concentrated traction rates applied to the surface of a prestrained bar are examined within the framework of finite strain theory. The analysis centres on a plane-strain compatibility equation for a stress rate potential.

ET for Tensile Prestrained Tubular Struts

Journal of Structural Engineering, 1986
Strain reversal in the inelastic range may cause a dramatic drop in the tangent modulus for mild steel struts. Other material properties also affect the tangent modulus. Consequently the influence of several of these properties is examined for an electric‐resistance welded steel tube. The variables chosen are: (1) Strain hardening caused by varying the
