| Abstract: | 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. |
