Based on EPMA analysis of arsenopyrite and the phase diagram of coexisting minerals pyrite-arsenopyrite,we conclud that temperature of the main mineralization stage is stable within 300～450℃. 本文通过主要矿化阶段热液矿物毒砂成分的测定,利用相图中共生金属硫化物稳定温度范围得出主要矿化阶段的温度为300~...
Block diagram simulatorsIn this paper, the degenerate kernel and superposition technique are employed to solve the screw dislocation problems with circular holes or inclusions. The problem is decomposed into the screw dislocation problem with several holes and the interior Laplace problems for several ...
And then the serialization simulation analysis of prefabricated piles were achieved; the cloud diagram and the maximal of Von Mises stress and displacement vector sum of pre-fabricated piles were elicited. The simulation results were analyzed and researched. The simulation results show that the ...

A bilinear descending stress-crack opening displacement diagram is considered to simulate the flexural behaviour of pre-cracked specimens. Although the shape of the diagram affects the theoretical value of the maximum load, such a dependence is smaller and smaller by decreasing the material fracture ...
Figure 1. Schematic diagram of the distribution of stress in a cylindrical tunnel. 2.2. D–P Criterion Yield Function The D–P criterion is the conical yield surface tangent to the hexagonal pyramid of the M–C criterion proposed by Drucker and Prager and based on the generalized Mises crite...
