- Synopsis
- In this paper, the fracture mechanism of concrete subjected to combined stress (so-called mixed mode fracture) and the modeling methodology are studied based on the literature. The test methods to examine the mechanism and the examples of the numerical analyses sre introduced. Finally, the numerical issues to simulate the mixed mode fracture and research tasks in the future are pointed out.
