摘要
有限元方法是进行科学计算的重要方法,其分析处理手段在众多工程技术领域都得到充分应用.在Ritz-Galerkin有限元法思想指导下,对给定边界条件下一种薄板弯曲问题的微分方程应用有限元方法分析讨论,得到了与有限差分法求解非常接近的结果,是用有限元法进行板壳弯曲问题数值计算的有益探讨.
Finite Element Method(FEM)is an important method for scientific calculation,and its analyzing and processing methods have been fully applied in many engineering and technical fields.under the guidance of Ritz-Galerkin FEM,the differential equation of a sheet-curved problem in the given boundary condition is analyzed and discussed by finite element method,which resulted in the conclusion similar to the outcome obtained from the finite difference method.Therefore,this is a useful discussion on numerical calculation of board-shell bending problems by Finite Element Method.
