... in stainless steels. Theoretical critical twinning stress is not the only criteria to decide the deformation modes of twinning or slip. The formation of twinning and slip can be affected by the factors such as loading profile, loading stress/strain rate, stacking fault energy, grain sizes, and cell...

... as the target material grains, and thus the target material must be considered as being anisotropic and inhomogeneous. Single crystals are chosen to study the effects of the anisotropic mechanical properties. It is also of interest to investigate the response of symmetric and asymmetric slip systems...

... of material property difference in stack fault energy and its relationship with cross slip under plastic deformation. Difference in response caused by different orientations (110 and 001) and active slip systems was also investigated. Contributed by the Manufacturing Engineering Division for publication...

... with the orientation of slip systems in adjacent grains leading to mismatch strains at the grain boundaries. The emergence of slip planes played a lesser role in the roughening process. A roughening model that assumed a spatial hardness variation was developed. Theoretical predictions of the dependence of the R...

...Zhi Deng, Mem. ASME; Michael R. Lovell, Mem. ASME; Kaveh A. Tagavi, Mem. ASME By means of the explicit dynamic finite element method, the relationship between the tool-workpiece interfacial slip and several cross wedge rolling (CWR) variables is investigated for a flat-wedge CWR process. After...

... deformation and micro slip before macro-breakaway occurs. The linearity of tangential stiffness is only valid in the stage of elastic deformation. The nonlinear tangential stiffness of the interface should be considered in the stages of elastic and plastic deformation before micro-breakaway occurs...
