摘要
本文给出圆柱壳问题混合状态方程的一种强有力的半离散半解析方法——混合状态等参元,它沿壳厚方向未作任何位移及应力分布假设,采用状态控制方程给出解析解答,与通常壳体元相比减少了未知量数目,提高了计算效率.
Based on fundomental equations of three-dimensional elasticity and giving up any assumptions about displacement models and stress distribution,the mixed formulation for cylindrical shell is established,and put out a semi-analysical method to solve this equation,which is named the variable control finite element method.
