- Abstract:
- A smoothed finite element method is applied to buckling analysis of plate,by using the first-orderReissner - Mindlin plate theory ( FSDT). The bending stiffness matrix and geometrical stiffness matrix for el-ement used strain smoothing technicque is calculated by a boundary integral along the boundaries of the smoot-hing cells in element. The mixed interpolation method is employed to calculate shear strains in order to avoidshear locking. Buckling loads of plates subject to uniformly uniaxial,biaxial compression and pure shear in-plane are studied using the smoothed plate element respectively. Numerical examples show that the smoothedplate element is free of shear locking and achieves the high accuracy,compared with mixed interpolation plateelement MITTC4.And the most significant property is their insensitivity to mesh distortion sg that the restrictionon the shape of classical isoparametric elements can be removed.
