【摘要】 本文采用双三次和双五次B样条函数构造扁壳的位移函数,由最小总势能原理来建立扁壳静力问题的基本方程。文中,给出若干数值算例,并与精确解和其他数值解作了比较,结果十分吻合。更多还原

【Abstract】 The double cubic and quintic spline functions are used to construct the displacement function for static analysis of double curved shells in this paper. The fundamental equations of double curved shell are established with potential energy.Some numerical results are given and they are good agreement with other method.更多还原
