Tóm tắt

A new Reissner-Mindlin plate formulation based on a quadratic NURBS-based isogeometric is presented. In order to avoid the transverse shear locking and to improve the accuracy of the present formulation, the quadratic NURBS-based isogeometric is incorporated with the Mixed Interpolation of Tensorial Components (MITC) technique to give a so-called quadratic NURBS-based isogeometric Mixed Interpolation of Tensorial Components method (Nurbs-MITC9). Numerical results of the proposed formulation show excellent performance compared to other available approaches.
