Linear viscoelasticity stability analysis of bluff rock slope 隨機(jī)連續(xù)桿縱向振動系統(tǒng)的頻率可靠性分析
( 7 ) basing on defining damage variable with flaws in rock , this paper uses linear viscoelasticity fracture mechanics to set up a damage reep model and analyses the model ( 7 )在用巖石中大小、方位和位置均為隨機(jī)分布的裂紋定義損傷變量基礎(chǔ)上,利用線粘彈性斷裂力學(xué)原理對考慮裂紋內(nèi)水壓的巖石的損傷蠕變問題進(jìn)行了建模和分析。
With engineering polymer - pmma taken as the main researched object and viscoelastic failure considered as the theory basis , the non - linear viscoelasticity and crazing damage phenomena under creep condition in macromolecule material were researched by means of experiment 本文以工程高聚物pmma為主要研究對象,以粘彈性破壞理論為基礎(chǔ),以實(shí)驗(yàn)為手段,對高分子材料蠕變條件下的非線性粘彈性性能及其銀紋損傷現(xiàn)象進(jìn)行了初步探討。
From the hypothesis of linear viscoelasticity , we predicted the time of life of the three specimens with edge crack which fractured in out experiment at last in view of energy releasing . however , we found that the predicted values were on the low side obviously , so we analyzed the reason of being non - linear . on this basis , we modified the method 本文的第四章從線粘彈性假設(shè)出發(fā),從能量釋放率的角度對實(shí)驗(yàn)中最終斷裂的三今含邊裂紋的試件的壽命進(jìn)行了預(yù)測,并與實(shí)驗(yàn)結(jié)果進(jìn)行了對比,發(fā)現(xiàn)預(yù)測值明顯偏低,分析了產(chǎn)生非線性的原因,進(jìn)行了非線性修正。
At present , many important development on the studies of viscoelastic theory have been made by the efforts of scholars home and abroad , linear viscoelasticity theory has sufficiently developed , while nonlinear viscoelastic theory is still under developed by the reason of difficulties in experiment and mathematics 目前,國內(nèi)外學(xué)者在粘彈性理論研究領(lǐng)域取得了許多重要的研究進(jìn)展,線粘彈性理論已發(fā)展得較為完善,非線性粘彈性理論由于實(shí)驗(yàn)和數(shù)學(xué)上存在的困難尚處于不斷的發(fā)展和完善之中。
