Steel cutting surface or shear surface should have no cracks , slag , stratification and the lack of greater than 1 mm prism 鋼材切割面或剪切面應無裂紋、夾渣、分層和大于1 ?的缺棱。
The results show that the frictions caused by the wall of shear box will influence the distributions of stresses in specimens and the normal pressure stresses on the shear plane 結(jié)果表明,剪力盒壁摩擦力將會影響試驗土樣中的應力分布和剪切面上的正壓應力值。
Another is shear - model fracture which is thought that it is associated with dislocation motion ( shear + rotation ) of crystal at microlevel , fragmentation of solid at mesoscale level and large plastic strains at the macroscopic level 剪切型斷裂在微觀上與晶粒內(nèi)或晶粒間的滑移和位錯有關,細觀上與集中變形帶中的微剪切面集中有關,宏觀上則與結(jié)構(gòu)內(nèi)的集中剪切帶有關。
The coherence force c and the inner friction angle of composite increase 115 % - 205 % and 11 % ~ 15 % respectively more than that of no rootstalk soil . 3 the mechanism of dealing with corn rootstalks and eight kinds of blades for experiment in the soil bin have been developed in order to investigating the performance of dealing with rootstalks 土壤-根茬復合體其抗剪強度與剪切面上的法向壓應力成正比,復合體土壤凝聚力c比無根土壤增加115 205 ;內(nèi)摩擦角增加11 15 。
