摘要： Hybrid-stress finite element method is applied for analysis of bending and vibration ofcomposite laminated plates in this paper.Firstly,based on the modified-complementaryprinciple,a reciangular hybrid-stress plate bending element is presented which applies toanalysis of laminates.Inside the element,different stress parameters are assumedaccording to different layers.The boundary displacements are determined by means of theassumption of YNS theory on the boundary of elements.The element formed in this way notonly can take effects of transverse shear deformation and local warping into account,butalso has less degrees of freedom.Then.problems of bending and vibration of laminates aresolved by using this element.and the numerical results are compared with the exactsolutions.This shows that the results obtained in the paper are very close to the exactresults.
