Calculating the absolute adsorption of high-pressure methane on shale by a new method
Published 2020-03-01“…Results present that the characteristics of excess adsorption isotherm under high pressure is different from the characteristics of excess isotherm under low pressure; adsorption obtained by adsorption experiment increases with pressure going up until reaching a peak and then declines with further increase in pressure. We build a new method to calculate the absolute adsorption by assuming that the adsorption phase volume approximately equals to the total volume occupied by adsorbed molecule, and the results calculated by our method show this method is reasonable and effective.…”

A METHOD MEASURING FRACTURE PARAMETERS OF BRITTLE MATERIAL USING U-NOTCHES
Published 2015-01-01“…Based on two stress criterions( the maximum circumferential stress criterion and average circumferential stress criterion) for U-notches under Mode-I,relationships among the critical notch stress intensity factor,the fracture toughness and the tensile strength were built separately,which follows the similar idea of Seweryn regarding the crack as a special U-notch with the notch radius equaling to zero. By means of the critical fracture loadings for U-notched plates under Mode-I and the finite element results of Ansys,a new method has been proposed to measure the fracture toughness and the tensile strength. …”

A Study of Contact Detection between Noncircular Particles in Discrete Element Method
Published 2022-01-01“…For the collision of a pair of ellipses with an aspect ratio of α = a/b = 1000, the efficiency is not worse than the Newton–Raphson method. For random packing under gravity, no residual kinetic energy is observed, and the force that acts on the bottom is equal to the gravity, that is, the system reaches a mechanical equilibrium state. …”
