viscous creep 中文意思是什麼
viscous creep
解釋
粘滯蠕變-
The presence of small amount of liquid at grain boundaries tends to form thin viscous layer which surrounds the finer grains. intergranular fracture may occur at the grain boundaries between two fine grains not covered by viscous phases. the high ductility achieved at low strain rates is generally attributed to dislocation glide - creep accommodation mechanisms
原始晶界上產生少量液相，形成薄的固液共存粘性層並包圍細化的晶粒，沿晶斷裂主要發生在無粘性層的細晶粒間；而在較低應變速率下，三叉晶界位錯攀援?蠕變協調機制鬆弛晶界滑移產生的應力集中，晶界上產生較多液相，有利於晶界滑移進行。 -
The study on retarded creep behavior using creep theory under condition of reservoir water lever in stabilized status for one and a half year demonstrates that the viscous coefficient of sliding soil shall increase as creep procedure continues, meanwhile, the displacement process of landslide surface area fitted by logarithmic curve matches closely with measured values
以蠕變理論研究在庫水位穩定一年半的條件下滑坡的減速蠕變現象，證明滑帶土粘滯系數隨蠕滑過程不斷增大，以對數曲線擬合滑坡表部位移過程與實測值吻合較好。 -
The research indicate that the structured soft clay has below several characteristic, the viscous strain is produced during the stage of primary consolidation and of second consolidation, and in the prophase, the relation of stress - strain - strain rate is unique, so the form of constitutive model, such as, f ( v ', e ) = 0, f ( ' v, e, t ) = 0, ca n ' t describe strain behavior of soil skeleton rationally ; the time - dependent properties involve three aspects, in addition the time - dependent strain, apparent preconsolidation pressures that depend on strain rate, and the effect of creep compression on apparent preconsolidation pressures ; because of holding structural strength, the mechanics characteristic is determined by the magnitude of stress, and the compression curve is composed of several sections. by combining structural yield stress and it ' s characteristics with the improved time line model, a new one - dimensional elastic visco - plastic consolidation model is established
研究結果表明，結構性土的固結過程具有以下特性：主固結和次固結階段都包含有因土骨架的粘滯性移動而產生的變形，而且在正常固結階段，存在應力?應變?應變速率的唯一性， f （ _ v ， e ） = 0 、 f （ _ v ， e ， t ） = 0形式的本構關系不足以描述土骨架的變形行為；固結壓縮過程中的時間效應包括三個方面的內容，除了應力應變關系與時間相關外，還包括粘滯性變形引起表觀前期固結壓力增加和屈服應力的應變速率效應；軟土的結構性使其力學特性與應力水平相關，壓縮曲線具有分段性。 -
( 5 ) basing on the exploring of the functions of cohesion force and friction force during rheology course and the assumptin that viscosity lost according viscosic strain, a constitutive model for viscous, elastic and plastic rock is set up, which can simulate the third course of creep. then the impact of transcient damage to rheology is discussed and corresponding creep model for rock is proposed
（ 5 ）在探導巖石顆粒間粘聚力和顆粒間摩擦力在巖石發生流變過程中的作用基礎上假設粘性失效按流變應變統計概率分佈，建立了巖石粘彈塑性本構關系，能夠描述巖石蠕變加速階段特徵；討論了瞬時損傷對巖石流變的影響和相應的損傷蠕變模型建模問題。
