On the basis of the research on stress transfer of flyash piles, the distribution law of frictional resistance is analysed, and with the help of the Mindlin solution and the assumption of the simplified distribution form of frictional resistance, a formula is derived for calculating the additional...
This study proposed a new discharge estimation method using a mean velocity formula derived from Chiu's 2D velocity formula of probabilistic entropy concept and the river bed shear stress of channel. In particular, we could calculate the mean velocity, which is hardly measurable in flooding natural...
the shape of the v-t curve for an ideal gas is a straight line. q4 what is the compressibility factor of an ideal gas? it is always 1. q5 what is meant by a fluid? a fluid is a material that constantly deforms under an exerted external force or shear stress. it cannot resist ...
Keywords: time-dependent DFT; dynamical exchange-correlation potential; homogeneous electron gas; stress tensor; bulk modulus; shear modulus1. Introduction Time-dependent density functional theory (TDDFT) [1,2] is the most important extension of Kohn–Sham [3] ground-state DFT to excited or time...
of brick and mortar strengths with certain proportions. Another unique prediction model was suggested by Roca et al. [25] in which masonry strength depended more on mortar strength. Dymiotis and Gutlederer [26] derived a second-order polynomial equation and suggested a formula after regression ...
then he exerts what is called ashear stress. A solid substance such as a brick can withstand stresses of both types, but fluids, by definition, yield to shear stresses no matter how small these stresses may be. They do so at a rate determined by the fluid’sviscosity. This property, ab...

and taking the variation in viscosity with pressure in the Hertzian contact into account, an approximate formula expressing the mean shear stress with shear rate was derived as a function of a viscosity-pressure coefficient and the representative stress determining the onset of non-Newtonian behaviour...
