The influence of strain path on subsequent mechanical properties—Orthogonal tensile paths
Metallurgical Transactions A, 1979Several aluminum alloys have been subjected to two stage tensile straining, an initial prestrain followed by a subsequent tensile strain at 90 deg to the initial direction. In AA1100-0 and AA3003-0 the prestrain produces dislocation tangling and diffuse cell walls resulting in an enhanced flow stress and decrease in ductility when the material, is ...

Strain-softening behaviour of sand in strain path testing under plane-strain conditions
Acta Geotechnica, 2008Experimental data are presented in this paper to study the strain-softening behaviour of sand under plane-strain conditions. K0 consolidated strain path tests were conducted using a new plane-strain apparatus. The stress–strain behaviour of medium dense sand under plane-strain conditions was characterized.

Dislocation Mean Free Paths and Strain Hardening of Crystals
Science, 2008Predicting the strain hardening properties of crystals constitutes a long-standing challenge for dislocation theory. The main difficulty resides in the integration of dislocation processes through a wide range of time and length scales, up to macroscopic dimensions.

The Effect of Pre-strain and Strain Path Changes on Ductile Fracture
2013Industrial metal forming operations generally require several deformation steps in order to create the final product. The mechanical behavior of materials undergoing strain path changes can be very different from those deformed in a given direction to fracture.

Annealing response of AA5182 deformed in plane strain and equibiaxial strain paths
Philosophical Magazine, 2013The annealing response of AA5182 Al–Mg alloy deformed to an effective prestrain of = 0.15 via plane strain and equibiaxial strain paths is compared. The comparison is done at two temperatures namely, 623 and 673 K. The recovery, recrystallization and grain growth behaviour of this alloy is studied by electron backscatter diffraction and dislocation ...

Strain-Path Modeling for Geo-Materials.
1984The explosions that most concern us all have effects known mainly by calculation. Since the calculations’ credibility influences the cost and scope of deterrence, reliable numerical prediction of explosion-effects is a long-sought goal. For free fields, flaws in stress-strain relations limit the accuracy of predictions: Such relations are hard to ...

Volume strain, strain type and flow path in a narrow shear zone
Geologische Rundschau, 1998This study explores the state of finite strain and changes in the mean kinematic vorticity number, grain size, whole-rock chemistry and mineralogy across an upper amphibolite-facies shear zone in a metadiorite, northern Malawi, east-central Africa. P–T conditions during shear-zone formation and deformation were approximately 700–750 °C and 5–7 kbar and
