摘要
根据非均质材料的细观特征 ,从基本的能量传递定律出发 ,建立了一种新的描述细观非均质材料破坏演化的物理元胞自动机 (PCA)理论 .该理论能够对岩石、混凝土等非均质材料破坏演化进行有效模拟 ,突破了传统元胞自动机仅限于数学规则运算的框架 ,使之成为一种有效的物理力学方法 .与岩石力学实验结果对比分析表明 。
Based on the physical and mechanical characters of micro-heterogeneous material such as rock and concrete,a new theory of physical cellular automaton (PCA) for simulating the failure evolving process of micro-heterogeneous materials is set up,according to the basic law of the transfer of energy. PCA breaks through the traditional cellular automaton method which is only a mathematical operation. It is shown by some Laboratory tests that the simulating results by PCA can agree with the laboratory results perfectly,thus,PCA is an effective physical and mechanical method.
