3-dimensional strain distribution in a local area of jointed boundary of composite materials

2相接合材의 接合境界面 局所領域에서의 3次元 變形率分布

The most 3-Dimensional problems of composite materials, especially three-dimensional stress or strain distribution on jointed boundary in composite materials remains unsolved due to the limitations of analytic techniques. The purpose of this paper is to apply the Embedded Grid Method to model development to measure the three-dimensional strain distribution along the jointed boundary of composite materials which consist of two different materials. It was confirmed that the Embedded Grid Method was very useful in model development and measuring the three-dimensional strain distribution in a local region near the jointed boundary.

본 연구에서는 이 염색격자법을 이용하여 가장 기본적인 복합재인 탄성계수가 서로 다른 두 물체로 구성된 2상적합재를 제작할 수 있는가를 검토하였고, 또한 제작 완성된 접합재를 이용하여 접합경계면 부근의 국소영역에서의 3차원적인 변형거동을 관찰한 것이다.
