例句與用法
- Continuum damage mechanics
連續(xù)介質(zhì)損傷力學(xué) - The theory of continuum damage mechanics and the basic principle about neural network are introduced
主要對連續(xù)介質(zhì)損傷力學(xué)和人工神經(jīng)網(wǎng)絡(luò)的基本原理進行了論述。 - In the end of this part , some application examples of fracture mechanics for the frozen soil have been given out . in the second part , continuum damage mechanics has been introduced to study the characteristics of the frozen soil . on base of additional damage concept , a judging model for initial and additional damage for frozen soil was proposed
第五章進行的是凍土損傷力學(xué)的測試研究，首先介紹了凍土損傷的動態(tài)測試原理與方法，采用附加損傷的概念推導(dǎo)了凍土初始與附加損傷的動態(tài)識別模式，隨后對凍土單軸壓縮過程進行了動態(tài)測試，對在這一過程中的內(nèi)部結(jié)構(gòu)變化特征進行了研究。 - At last , an effective stress were calculated and compared with the really stress using the theory mentioned above . the third part is a discussion and prospect on the frozen soil study using fracture mechanics theory and continuum damage mechanics . all of the work are supported by nsf and sklfsa
最后對本文工作進行了總結(jié)，分別對凍土斷裂力學(xué)、損傷力學(xué)研究的發(fā)展與展望提出了自己的觀點與設(shè)想，指出將斷裂力學(xué)、損傷力學(xué)引入凍土力學(xué)研究至今還僅僅是初步工作，還需要進行大量的研究工作。 - Most existing constitutive models do not take into account the interactions between different phases of pearlitic steel and cannot illustrate why such kind of materials has excerllent mechanical properties . it is , therefore , necessary to develop a new method , which can describe the macroscopic behavior , damage and failure of the materials and their micro structural dependence . in this paper , based on a non - classical theory of plasticity and the continuum damage mechanics , a damage evolution based on an ellipsoidal void model for mixed hardening materials is obtained
已有的關(guān)于珠光體鋼的本構(gòu)模型多難以考慮珠光體材料的微結(jié)構(gòu)及其相互作用，難以解釋珠光體材料何以具有較好的綜合力學(xué)性能，因此有必要發(fā)展一種多層次的細(xì)觀力學(xué)分析方法以研究此材料在復(fù)雜加載條件下計及微結(jié)構(gòu)特征的宏觀響應(yīng)特性，使材料的強度、疲勞壽命的預(yù)測與其微結(jié)構(gòu)及各組成相的損傷及微觀應(yīng)力應(yīng)變演化規(guī)律聯(lián)系起來，進而為材料微結(jié)構(gòu)的設(shè)計提供依據(jù)。
