Abstract EN
This paper is devoted to develop a new 8-node higher-order hybrid stress element (QH8) for free vibration and buckling analysis based on the Mindlin/Reissner plate theory.
In particular, a simple explicit expression of a refine method with an adjustable constant is introduced to improve the accuracy of the analysis.
A combined mass matrix for natural frequency analysis and a combined geometric stiffness matrix for buckling analysis are obtained using the refined method.
It is noted that numerical examples are presented to show the validity and efficiency of the present element for free vibration and buckling analysis of plates.
Furthermore, satisfactory accuracy for thin and moderately thick plates is obtained and it is free from shear locking for thin plate analysis and can pass the nonzero shear stress patch test.
