蠕變失效 的英文怎麼說
中文拼音 [rúbiànshīxiào]
蠕變失效
英文
failure by creep-
Application of updated concurrent subspace optimization in the structural optimization with constraints of aerodynamics and rcs of aircraft
可靠性敏度分析方法及其在非線性蠕變疲勞失效模型中的應用The knowledge on the properties of used materials is urgently needed for reasonable life - prediction and life - distribution. as cylinder bolts are concerned, they often rapture at the first tooth - root resulting from lower high temperature strength of their material and higher stress. since bolts operate at high temperature environment, creep skew and damage causing their failure are important factors that can not been neglected
就汽缸螺栓而言,由於螺栓材料的高溫強度偏低,預緊力過大,常常在螺栓的第一齒根部位發生蠕變脆性斷裂,因其長期在高溫環境下工作,蠕變變形和蠕變損傷是其失效的一個不可忽略的重要因素。According to the failure factors, the mechanism, the processes, the critical conditions, the aftereffects etc, the main steam pipe ' s failure patterns are divided into five types : frangibility, toughness, high temperature, creep, fatigue, the processes and characters of each type is analyzed and summarized
根據主蒸汽管道失效因素、失效機理、失效發展過程、失效臨界條件、失效後果等幾個方面,確定了主蒸汽管道失效的五種形式,即脆性失效、韌性失效、高溫失效、疲勞失效和蠕變失效,並對每種失效形式的過程和特徵進行了分析。( 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。Undoubtedly, deterioration and damage accumulation occur in high temperature and high pressure. with the consumption of their use, the failure accidents occur more frequently, which will bring threatening to the life of people and the poverties of enterprise. so the failure analysis and the residual life assessment of the main steam pipe become more and more urgent and important
以蠕變性能作為設計指標的主蒸汽管道是發電廠的關鍵部件,由於長期在高溫高壓的惡劣工況下運行,容易發生材質老化和損傷積累,突發性事故也會頻頻發生,給企業職工的生命安全和國家財產帶來嚴重威脅,因此對主蒸汽管道進行失效分析與壽命預測尤為迫切和重要。分享友人
