The Stiffness Analysis of Circular Plate Regarding the Area Change of Both Ends Constructing Supporting Conditions

원형평판의 지지조건을 구성하는 양 끝단의 면적변화에 따른 강성도 해석

This paper investigates the characteristics of deflection for circular plate that has same supporting condition along the width direction of plate according to the area change of supporting end. For two boundary conditions such as simple supporting and clamping on both ends, this study derives maximum deflection formula of circular plate using differential equation of elastic curve, assuming that a circular plate is a beam with different widths along the longitudinal direction. The deflection formula of circular plate is verified by carrying out finite element analysis with regard to the ratio of length of supporting part to radius of circular plate.
