中文拼音 [sùxìngyīngbiàntú]
塑性應變圖
英文
plastic strain profile-
Obtained pre - tight and in the work process pressure distribution, the frictional stress, the elastoplasticity distortion and the stress distributed cloud chart and so on, and has carried on the thorough comparison and the analysis to the result
得到了施加預緊和工作過程中的壓力情況，摩擦應力，彈塑性變形和應力分佈雲圖等，並對結果進行了深入的比較和分析。Author thinks that the direction of the maximum plastic distortion along a constant radius around the crack tip may be considered as the direction of shear - mode fracture ( named pmax - criterion ) and the load when located shear band prongs the ligament in the front of crack tip is regarded as the limited load of shear - mode fracture. ( 3 ) the fad ( fracture assessment diagram ) of titled crack is proposed based on achievements of mesomechanics about i - ii complex ductile fracture of metal, and the titled crack is classified two kinds : void - mode fracture is assessed by fracture assessment curve, and shear - mode fracture by limited load. ( 4 ) using a fe program based on plantle - ressue theory to calculate some mesomechanical parameters, a flange joint structure of a high pressure vessel ( design pressure 31. 4mpa and the thickness of the hemispherical head is half of that of shell. ) is analyzed to determine whether the structure under operation pressure is safe or not, forecast the mode of potential invalidation and argue for the rationality of design of the structure
試件的整體斷裂為剪切型，但在試件芯部裂尖鈍化區中部出現了韌窩型啟裂並有一定的擴展，說明局部較高的應力三軸度也會使韌窩型機制得以發展，但是不改變試件整體的剪切型斷裂模式；對韌性斷裂的剪切模式的細觀機理做了一定的探討，並且提出了含裂紋構件剪切型斷裂的宏觀判據：認為裂紋前方的集中剪切帶中與裂紋尖端等半徑處最大有效塑性應變出現的方向可以作為裂紋剪切斷裂的方向（可簡稱為_ （ pmax ）準則） ，集中剪切滑移帶貫穿裂紋前方承載韌帶時的載荷可以作為極限載荷；本文運用金屬韌性斷裂細觀力學在一復合型韌性斷裂方面的研究成果，採用失效評定圖的形式，提出了傾斜裂紋的安全性評定方法的基本框架。The final configuration is identical to that in (a), and the total plastic strain is six atomic spacings.
最後的排列雖與圖a一樣，但總的塑性應變量是6個原子距。Then a dynamic visualization software - - afterdraw, which aims at 2d elastic - plastic fem, is programmed. afterdraw is capable of drawing the deformation figures of material, the regions of plasticity and the regions of tension distributing figures, primary stress vector figures and primary strain vector figures. besides, atterdraw could realistically dynamically simulate the deformation of the whole process of construction
在此基礎上，研究了針對二維彈塑性有限元的動態可視化后處理軟體afterdraw ， afterdraw能夠繪制基坑工程各步施工的結構變形圖、塑性區和受拉破壞區分布圖、主應力矢量圖和位移矢量圖， afterdraw還能夠逼真地動念模擬基坑工程整個施工過程變形情況。In this dissertation, area geology background, engineering geology condition and mechanism of deformation - destruction of the landslide are adequately analyzed, and finite element method is applied to analyzing the landslide stability in the study area, then changes of stress field, displacement field, plasticity destruction zone and stability coefficient contour are discussed
論文充分分析了巫山縣四道溝滑坡的區域地質背景、工程地質狀況，系統分析了滑坡的變形破壞機理，採用有限元法進行了滑坡穩定性分析，討論了在各種工程情況下的應力場、位移場、塑性破壞區以及穩定性系數等值線圖的變化情況。分享友人
