摘要
本文研究板壳几何非线性弯曲问题,用变量变换和三次B样条函数。解决了平行四边形板壳的平衡问题,推导出统一计算格式,便于在计算机上计算。
The paper has studied the geometric nonlinear bending problem of plates and flat shells. By using vatiable transformation and cubic B-spline function, the equilibrium problem of parallelogram of plates and flat shells is Solved, and the general computation form is derived for computing with cornputer
