tensional stress 中文意思是什麼
tensional stress
解釋
張應力-
The cable - strut tensile structures are the self - stress equilibrium systems composed by tensional cables and struts. in this paper, the basic concept of the structures was described. the analysis methods of the structural characteristics ( statically and kinematically determinate or indeterminate ) and the geometrical stability were presented. it is indicated that the cable - strut tensile structures are in stable equilibrium with first - order infinitesimal mechanisms. the ranks of equilibrium matrix were calculated by employing the singular value decomposition, and the independent modes of inextensional mechanisms and the states of self - stress were also obtained in the same way. this paper contains some typical examples which illustrate all of the main points of the work
索桿張力結構是指由張力索和壓桿組成的、具有預應力自平衡的新穎結構體系.本文詳細闡述這種結構的基本概念和結構特徵，討論結構靜動定體系特性和幾何穩定性判定分析方法，指出索桿張力結構應具有一階無窮小機構的幾何穩定體系.文中採用奇異值分解方法計算結構平衡矩陣的秩，並計算獨立機構位移模態和自應力模態.最後，對幾種典型的索桿張力結構進行了算例分析 -
Compound deformation on right dam abutment is the result from three deformation modes acting together. the three deformation modes are pressing - plastic fluxion rip mode, toppling - tensional and shearing fracture mode, stress release - tensional fracture mode
右壩肩復雜變形是壓致?塑流拉裂、傾倒?張剪和卸荷?張裂破壞三種變形模式復合作用的結果。 -
According to thorough research on mechanical mechanism of 3 - d tensional micro - fracture producing, this point is put forward the first time that : there is more stress concentration in the circumference of micro - cracks. and the cracks are easier to expand and to link with each other when the fissures contained saturated pore fluid than dry state. therefore, it is necessary to modify the griffith criteria
4深入研究了三維張性微裂縫形成的力學機理，首次指出：在裂隙內飽含孔隙水的情況下，微裂縫周邊的應力集中程度更高，裂縫更容易擴展乃至連通，因此，在張裂縫發育的研究中應該對格里菲斯準則進行修正。
