| Abstract: | The corresponding higher-order shear deformation theory of Reddy quadrilateral finite element range of applications was expanded to be used in composite laminates and structure in the pull-bend geometry under load coupled nonlinear analysis.Numerical results show that such new element can be used to calculate the stress and displacement more accurately,and can be promoted for the geometrically nonlinear analysis. |
