A Study on the Vibration Characteristics Analysis of Composite Materials by Using Electronic Speckle PatternInterferometry Method
전자처리 스페클 패턴 간섭법을 이용한 복합재료의 진동 특성 해석에 관한 연구
Abstract
The Electronic Speckle Pattern Interferometry(ESPI) has been applied to many technical problems such as deformation and displacement measurement, strain visualization and surface roughness monitoring. Composite materials have various complicated characteristics depending on the ply materials,ply orientations,ply stacking sequences and boundary conditions. Therefore, it is difficult to analyze composite material. For efficient use of composit materials in engineering applications, the dynamic behavior such as, natural frequencies and modal patterns should be identified. This studying presents FEM results for the free vibration of symmetrically laminated composite as [30/-30/90]
