RM이론에 기저한 등기하해석법을 이용한 판의 해석

Abstract

A plate element based on Reissner-Mindlin (RM) theory is developed by using isogeometric approach. The non-uniform rational B-spline (NURBS) is used to represent the geometry of plate and the unknown displacement field. Therefore, all terms required in this element formulation are consistently derived by using NURBS basis function. Several numerical examples are conducted to investigate the accuracy and reliability of the present plate element. From numerical results, it is found to be that the present plate element produces the isogeometric solutions with sufficient accuracy. Finally, the present isogeometric solutions are provided as future reference solutions.
