| Abstract: |
| A model of composite laminated Mindlin plate of buckling analysis based on new modified couple stress theory is presented.The theory involving two material length scale parameters,one related to fiber and the other related to matrix.Based on modified couple stress theory,the Mindlin laminated plates is different from composite laminated Kirchhoff plate,considering the transverse shear deformation,and involving two angle of rotation variables.A simplified model for cross-ply composited laminated Mindlin plate including only one material length scale parameter is applied to the buckling analysis.Calculating the critical load of cross-ply laminated Mindlin plate with simply supported boundary.Numerical results show that the scale effects of buckling analysis in microstructures are captured by present model. |
