The results obtained in this research are summarized as follows :1. The elasto-visco-plastic suspension element method for the fracture analysis was developed. Non-linear yield function was adopted, and repetitive loading was considered.2. The input data are fixed by fundamental experiments with two dimensional model specimen.3. The stress-strain curves of two dimensional concrete specimens under high-speed repetitive loading were simulated and discussed under various conditions of loading speed, shape and size of specimen, and position of coarse aggregate.4. The multi-axial loading tests were simulated.5. The analytical method was expanded in order to simulate the experimental results.

本研究取得的主要成果如下：1.建立了弹粘塑性悬挂单元断裂分析方法。采用非线性屈服函数，并考虑重复加载。2.通过二维模型拟合的基础实验确定了输入数据.对不同加载速度、试件形状、尺寸、粗骨料位置等条件下的二维混凝土试件在高速重复荷载作用下的应力-应变曲线进行了模拟和讨论.对多轴加载试验进行了模拟.为了模拟实验结果，对分析方法进行了扩展。
