中文拼音 [rúbiànbiànxíngcáiliào]
蠕變變形材料
英文
creep-strained material-
It is shown that paraffin can be uniformly absorbed into the pore network of expanded graphite, that expanded graphite remains its vermiform structure in pcms, that the phase - change temperatures of composite pcms are similar to that of paraffin, and that the latent heat of composite pcms is are based on the mass fraction of paraffin in the composite materials
結果表明:膨脹石墨吸附石蠟后仍然保持了原來疏鬆多孔的蠕蟲狀形態,石蠟被膨脹石墨微孔所吸附;復合相變儲熱材料的相變溫度與石蠟相似,其相變潛熱與基於復合材料中石蠟含量的潛熱計算值相當。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。Concretely, 1, base on the viscoelastic mechanism of polymer depend on time, single axes stretching experiments are proceeded to research viscoelastic distortion of high polymer with the dependence on non - linearity and stress. we get each material parameter by dealing with the data of experiments, and contrast several theories of one dimension creep. 2
根據聚合物時間相依的粘彈性機理,對pmma試件進行了單軸拉伸蠕變實驗,著重研究了高聚物粘彈性變形的非線性及應力水平相關性;在此基礎上,對實驗數據進行擬合,得到了各個材料參數,並對幾種現有的一維蠕變理論進行了對比分析; 2The substructure near the damage position was studied by ebsp, then vonbined with the relationship among substructure grain boundary sliding grain size and material deformation compatibility the mechanics of creep damage was discussed
使用電子背散射衍射技術研究了不同損傷位置附近的亞結構形成情況,結合亞結構、晶界滑移、晶粒尺寸與材料變形協調性等材料變形特點,對蠕變損傷機理進行了探討。The predictions have shown a good agreement with the experiment results. the creep testing method was studied thoroughly in this paper. the whole creep testing system is developed by creep machine, extensometer, resistance strain gage, a / d translation board, computer and a set of software which can collect creep data automatically
本文對樹脂基三維編織復合材料的蠕變測試方法進行了深入研究,採用自行研製的蠕變機,利用引伸計、電阻應變儀、 a d轉換器、計算機等儀器,自行編制的蠕變數據自動採集軟體形成了一套蠕變測試系統。It seemed that the fiber and the matrix did not creep themselves in the range of the testing stress and temperature, so the matrix microcracking and interfacial sliding will be the main contributer to the macroscopic deformation of the three - dimensional c / sic composite
由於在所測定的溫度區間和應力范圍內,碳纖維和基體本身都不大可能發生蠕變。因此,基體開裂和界面的滑動是3d - c sic復合材料宏觀變形的主要貢獻者。分享友人
