摘要
本项研究建立在“材料结构弱点”概念及“材料结构弱点特性”理论的基础上,阐明了依据“材料结构弱点”概念及其特性理论研究微裂纹在材料微结构内虚拟扩展问题的具体思路与方法,证明了“材料微结构-材料结构弱点特性-微裂纹扩展行为”之间存在的固有的对应性规律,为研究微裂纹在材料微结构内的虚拟扩展提供了新的理论与途径。
Based on the innovative concept and theoretical descriptions of Material Structure Weakness （MSW） this article describes details of our adopted methodology and developed research framework in an explicit manner to simulate and predict virtual propagation of microcracks in computer-constructed microstructure of materials. The research efforts illustrate that there exists a coherent one-to-one relationship between ＂microstructure-MSW behavior-microcrack propagation behaviors＂. The proposed methodology and research framework show a new way for simulating and predicting virtual propagation of microcracks in the microstructure of materials.
