%X In this paper a circular plate that is fixed round the circumference and evenlyloaded is considered as defect model of cementation strucfure of metal plates. Fringedistrbuttons of the defect model in holography and speckle-shearing interferometryare computed,thus for each an experience formula determining defect size is established.The correctness of these formulae are well verified through experiments.
