摘要
开展含微裂纹缺陷材料(混凝土)破坏行为的研究,是当今力学界研究的重要课题之一。通过试验分析微裂纹扩展与损伤演变的关系,可得到损伤的扩展及弹性模量的降低并不仅仅取决于最初的微裂纹密度大小等结论,从而为理论研究提供了必要的试验依据。
It is one of the most important aspects among the mechanics to research on the destroy behavior of concrete which has inner micro-cracks defect already. By experimental methods, the paper discusses the relationship between the development of micro-cracks and the fatigue evolvement, it is concluded that both the fatigue evolvement and the elastic modulus depression are not only decided by the initial density of inner micro-cracks, the results may be information for further theory search.
