TA-ESPI를 이용한 박판의 포아송의 비 측정

다국어 초록 (Multilingual Abstract)

This research measures the Poisson`s ratio which give us some informations for the physical characteristics of the materials by Time Average-Electronic Speckle Pattern Interferometry(TA-ESPI). In order to find out the Poisson`s ratio, this research uses Euler-Bernoulli equation of cantilever beam (by TA-ESPI). The TA-ESPI technique has been developed as a common measurement method for vibration mode visualization and surface displacement. A harmonically vibrating object has the maximum out-of-plane displacement at a resonance frequency. The resonance frequency depends on material, size, thickness and the boundary condition. The proposed technique for measurement of the Poisson`s ratio in sheet materials are expected to be used as the advanced non-destructive testing method with the merits of time-saving and non-contact in the MEMS field.
