| Research Abstract |
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.
