Heterogeneous shear zone evolution: The role of shear strain hardening/softening

Journal of Structural Geology, 2008
Mathematical models are proposed to describe heterogeneous shear zones characterized by variation thickness with time. These models take into account several combinations of deformation type regime (simultaneous simple shear, pure shear, and volume change) and degree of strain localization.

The role of shear stresses and shear strains in transformation-toughening

Philosophical Magazine A, 1991
Abstract The effect of shear stresses and shear strains on microstructural development in transformation-toughened materials is studied with a procedure that treats the particles as a distribution of small, circular, transforming spots that surround the tip of a semi-infinite stationary crack.

Circular plates with shearing strain

Computers & Structures, 1990
Abstract The shearing strain of plates is studied. The space position of the normal, which before deformation is perpendicular to the middle surface of plates can, after deformation, be fixed with the help of the rotations ψr(r, φ) and ψφ(r, φ) about the axes →er and →eφ.

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.

Shear Stress-Strain Phenomena

1991
A fundamental message of this work is the advantage gained from the separation of volumetric and deviatoric phenomena in the study of the physical and mechanical behavior of soils. With respect to the treatment of the volumetric phenomenon, consolidation, there is almost no discrepancy between this and the tri axial consolidation tests as they are in ...

Shearing Strained Elastic Elements

2011
Under the name of shearing strained elastic elements one can identify all the elastic elements where strain gauges are located at ± ( 45° angles on the load application direction. There are bidirectional rosettes specially marked for these angles. Two layouts are presented in Figures 26.1a (“cross” type) and 26.1b (“square”). Within these shear-bridges
