摘要
对国内外宏细观本构模型的研究进展进行了总结,从而比较了混凝土宏观和细观研究的优缺点,表明了混凝土多尺度分析方法的重要性。建立了宏细观多尺度建模和分析方法,该方法能够模拟混凝土宏观非线性特征和细观损伤破坏的全过程,形象地解释了混凝土损伤破坏的本质。
The research progress of the macro and micro mechanics constitutive models is summarized at home and abroad,and then the inadequacies of the presented study are summarized,which indicates the importance of the multi-scale analysis method.The macro and micro multi-scale modeling and analysis method is established.This method can simulate the whole process of nonlinear macro-mechanical behavior and micro-damage of concrete,vividly explaining the micro-damage essence of mechanical behavior of concrete.
