The deformation mechanism and texture evolution of AZ31 Mg alloy compressed in three different directions at room temperature were studied, the relationship between two was compared through experiments viscoplastic self-consistent (VPSC) modeling. Setting up only one specific mode predominant by changing CRSS ratio for modes. following conclusions drawn: (1) It demonstrated that basal slip caus...

To improve the utilization rate of bamboo, glued laminated bamboo hollow column (GLBHC) was examined under eccentric compression to study effects different slenderness ratios, distances, and wall thicknesses on its ultimate bearing capacity. The nonlinear deformation material P-delta effect occur compression, which can affect capacity, so it is very important analyze elastic-plastic buckling co...

Plastic heterogeneity in indentation is fundamental for understanding mechanics of hardness testing and impression-based deformation processing methods. The heterogeneous deformation underlying plane-strain indentation was investigated in plastic loading of copper by a flat punch. Deformation parameters were measured, in situ, by tracking the motion of asperities in high-speed optical imaging. ...

Plastic shear significantly reduces the phase transformation (PT) pressure when compared to hydrostatic conditions. Here, a paradoxical result was obtained: PT of graphitelike hexagonal boron nitride (hBN) to superhard wurtzitic boron nitride under pressure and shear started at about the same pressure ( approximately 10 GPa) as under hydrostatic conditions. In situ x-ray diffraction measurement...
