, the slipping mode changes from shallow slippage to the deep slippage mode; with the increase of friction angle, the safety factor of slope increases gradually, and their relationship meets the linear way, and the slipping plane moves from internal of slope to the slope surface. Key words: structural plane; strength parameters; stratified slope; stability 层状岩体又称板裂岩体,是指分布有一组占绝对优势结构面(如层面,片理面等)的岩体.其优势结......
:A robust unified controller was proposed for wheeled mobile robots that do not satisfy the ideal rolling without slipping constraint. Practical trajectory tracking and posture stabilization were achieved... was finally constructed to robustify the nominal control law with respect to the slipping disturbance by using the Lyapunov redesign technique. The design procedure can be easily extended to the robot......
superdislocations shearing into γ′ phase may cross-slip from the {111} to {100} planes to form the K–W locks with non-plane core structure, which may restrain the dislocations slipping to enhance......
rotating the lattice around the[1010] and 0001 axis, respectively. Once both of them cannot be activated, the pyramidal-2 slipping occurs rotating the lattice around the [1010] axis. The relationship......
at 220 ℃, increases up to 131.4%, which attributes to the finer grains resulted from the dynamic recrystallization occurred during hot extrusion. As hot extrusion goes on, the slipping... are the twinning deformation and dislocation slipping in the twinning regions. Moreover, the deformation mechanisms of the alloy are a dislocation activation on the basal plane and a+c dislocation......
that dynamic recrystallization(DRX) controlled by dislocation slipping and climbing mechanism occurs in the temperature and strain rate range of 1050-1200 ℃ and 0.001-0.01 s-1; And DRX controlled......

zone and matrix zone. Twinning was considered as the dominant plastic deformation mechanism of depleted uranium subjected to impact loadings. Besides twinning, the dislocation slipping also played... are shown in Figs. 7(b) and (c), indicating that dislocation slipping also plays an important role in DU under dynamic deformation. As reported, the [100](010) dislocation slipping was considered......
slipping may change from the {111} planes to the {100} planes.关键词:......
treated alloy cooled in oil bath is that the double orientation slipping of the dislocations is activated, the configuration of the dislocation tangles and stacking fault may be formed in the molten salt cooled alloy. Thereinto, the fact that the particles-like carbides are discontinuously precipitated along the boundary may effectively restrain the dislocation slipping, which is the main reason......
