, but also happen inside the model. The produced cracks are mainly tensile cracks. The number of the contact force and the distribution range of contact azimuth angle of the anchoring joint decrease with the shear displacement increasing, and the direction of the contact azimuth angle is gradually changed to the direction of shear load. Key words: roughness; distinct element method; direct shear......
A New AgMeO Contact Material 唐红梅1,温鸣1,王宝珠1,王景芹1,陆俭国1,吕玉申1 (1.Department of Electrical Engineering, Hebei University of Technology,) Abstract:A new silver rare earth oxide contact material... and mechanical properties of Ag/SnO2(12) and Ag/CdO(12), the properties of three contact materials are similar, and hence Ag/La2O3(12) may become a potential contact material to be used as the substitute of Ag......
, Harbin 150001, China)Abstract:A line contact model of elastic coated solids is presented based on the influence coefficients (ICs) of surface displacement and stresses of coating-substrate system and the traditional contact model. The ICs of displacement and stresses are obtained from their corresponding frequency response functions (FRF) by using a conversion method based on fast Fourier......
CONTACT MATERIALS FOR GaSb AND InSb: A PHASE DIAGRAM APPROACH K.W.Richter1,H.Ipser1 (1.Institut für anorganische Chemie,Universitat Wien Wathringerstrasse 42,A-1090 Vienna,Austria) Abstract... as these contacts will be stable even after long exposure to elevatedtemperatures. These possible candidates for contact materials may be directly obtainedfrom the phase diagrams.During the last years we......
the slag penetration [1-9]. In penetration of the slag into the refractory, the absorption force of capillary phenomena is determined by the surface tension and the contact angle of the slag on the refractory. Figure 1 shows a schematic diagrams of the relation between the contact angle and the penetration of the liquid into the pore following ΔP=(2γLV·cosθ)/r  ......

Probabilistic analysis of random contact force between geomembrane and granular materialJIANG Xiao-zhen(姜晓桢)1, 2, SHU Yi-ming(束一鸣)1(1. College of Water Conservancy and Hydropower Engineering, Hohai... entropy was employed to analyze the randomness of contact force between geomembrane and granular material. The contact force distribution is exponential according to the proposed method and the grain......
