| Summary: | 碩士 === 國立臺北科技大學 === 機電整合研究所 === 98 === In this study, the analysis of the shear correction coefficients of the laminated plate was discussed. By using the assumptions of first-order Midlin theory, the equations of stress and strain can be obtained, and according to the formula of Coordinate transformation, transform matrix of different arrangements can be found. Then using the static equilibrium equations and assumptions of constraint conditions, shear strain is expressed by the force and moment acting on the object. The last, we use the shear strain energy equilibrium relationship, the shear correction coefficient calculating formula can be derived.
To explore the changes about the shear correction coefficients of hybrid laminated plate at the different conditions. The analysis results show that the ratio of E1/E2 has a great impact to the value of the shear correction coefficients. According to the different amount (odd and even types) and the arrangement (symmetric or cross types) of layers and the different thickness of the Laminated Plate, the results of the shear correction coefficients are different. Finally, we change the shear correction coefficients of the FSDT to compare with the effects of palte deflection.
