Ultrasonic characterization of modified Cr2O3 coatings by reflection coefficient spectroscopy LI Ji-cheng(李继承)1, LIN Li (林 莉)1, LI Xi-meng(李喜孟)1, LI Guang(李 光)2, LEI Ming-kai(雷明凯)3 1... reflection coefficient spectroscopy (URCS). The URCS was analyzed based on an acoustic transmission model for the multi-layered structure. The longitudinal velocity in the coatings was calculated from......

field model are mainly focused on the plane of weak anisotropy (the coefficient of anisotropy is less than 0.067), and the investigations on the plane of strong anisotropy are very few[16-18]. Until... of anisotropy (4) where ε4 is the coefficient of anisotropy, n is the vector of interface......
. To find a characteristic precursor for rockburst, the dynamic evolution of rock anisotropy during the rockburst test is quantified by the anisotropic coefficient k, defined as the ratio of the two P... be generalized as anisotropy-isotropy-anisotropy. The suddenly unloading induces damage in the rock and presents anisotropic coefficient k steeply increasing departing from one, i.e., isotropy......

There has a critical value during the course... function between interface normal and special direction with interface energy. The current phase-field model aims at non-facets with weakly anisotropy chiefly (anisotropic coefficient is smaller than......

Abstract: To assess the water inflow which is more suitable to the actual conditions of tunnel, an empirical correlation about the permeability coefficient changing with depth is introduced. Supposing......
, the shear fracture preferentially occurs as the stress anisotropy coefficient increases. Both the maximum tensile stress and equivalent maximum shear stress decrease as the stress anisotropy coefficient increases, which indicates that the greater the stress anisotropy coefficient, the higher the external loading required to propagate a new fracture. The numerical results obtained in this paper provide......
