V-노치를 갖는 유한평판의 컴퓨터 광탄성 해석

A conventional photoelasticity method has some difficulties to get the accurate results due to a collapsed image of the fringe when performing stress analysis around a crack tip or concentrated loading point. A method of digital image processing technique, which can multiply and sharpen the isochromatic fringe in photoelasticity is applied to obtain a better photoelastic fringe pattern of a v-notch plate under tension.
