1. 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(jì)及微結(jié)構(gòu)特征的宏觀響應(yīng)特性，使材料的強(qiáng)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(jìn)而為材料微結(jié)構(gòu)的設(shè)計(jì)提供依據(jù)。
2. It's difficult to find structural dependence in a sentence. 用structural dependence造句挺難的
