| Research Abstract |
The aim of this study is the development of high accurate fracture mechanics simulator for Ryukyu limestone under some complex external mechanical impacts. The development item or acquisition were as follows: (1) Obtained some material/mechanical parameters of Ryukyu limestone by some experimental approaches. (2) C-MultiMLS method (Multi-dimensional Moving Least Squares Method with Constraint condition) was applied to fracture mechanics, and a simulator with some mesoscpic-structures taken into consideration was developed. (3)Based on (1), the simulator of (2) was applied to an actual natural disaster problem.
Some domestic/international journal papers or conference proceedings were accepted in this study. This is one of the achievements of this study.
