In the paper , viscoelastic theory and ann ( artificial neural network ) are applied to estimate ds and draw the curve of deformation 本文將粘彈性理論和人工神經(jīng)元網(wǎng)絡(luò)應(yīng)用于車(chē)轍試驗(yàn)動(dòng)穩(wěn)定度的預(yù)估。
Viscoelastic theory is a boundary science that depends on the development of mechanic and material science , it is one of the important parts of continuum mechanic 粘彈性理論是在力學(xué)和材料之間發(fā)展起來(lái)的邊緣科學(xué),是連續(xù)介質(zhì)力學(xué)的一個(gè)重要組成部分。
Preliminary research on creep and dynamic characteristics , which are two important properties of asphalt concrete cores for embankment dams , through triaxial compression creep tests and dynamic triaxial test with the aid of the viscoelastic theory and the soil dynamics theory 本文通過(guò)三軸壓縮蠕變?cè)囼?yàn)和振動(dòng)三軸試驗(yàn),借助粘彈性理論和土動(dòng)力學(xué)理論,對(duì)土石壩瀝青混凝土心墻材料的兩個(gè)重要性質(zhì)? ?蠕變性能和動(dòng)力特性進(jìn)行了初步的研究。
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(guó)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。
