| 摘 要： | 本文从微结构理论出发,用相对变形描述微结构之间的微空隙和微裂纹引起的材料损伤的影响,得到用损伤张量描述各向异性损伤的微结构弹性损伤模型.化简该损伤模型可得到目前公认的几种主要损伤模型.对于混凝土材料的单向拉、压的基本受载情况的计算结果与D.krajcinovic的平面裂纹矢量损伤模型的计算结果及实验数据吻合较好,特别在失稳后阶段对实验结果也有较好描述.

| Abstract: | The paper formulates a micro-structural continuous damage theory describing an anisotropic damage field. The model can be reduced to some of the major models well known at present, and the numerical analyses are compared with the experimental data of the concrete specimen under uniaxial tension compresson. |
