Development of high accurate fracture mechanics simulator for Ryukyu limestone

本研究的目的是开发高精度的琉球石灰岩在复杂外部力学冲击作用下的断裂力学模拟器。(1)通过实验手段获得琉球石灰岩的部分材料/力学参数。(2)将C-MultiMLS方法(带约束条件的多维移动最小二乘法)应用于断裂力学，开发了考虑细观结构的断裂力学模拟器。(3)在(1)的基础上，将(2)的模拟器应用于一个实际的自然灾害问题，接受了一些国内外的期刊论文或会议记录。这是本研究的成果之一。

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.
