摘要
导出斜型薄板单元模型并应用于有限元线法(FEMOL)求解平行四边形斜板的弯曲问题.还给出利用半离散总势能泛函的极值条件导出的有限元线法控制微分方程组及其ODE求解体系.计算实践表明,仅用很少数量的斜单元网格就可以得斜型薄板弯曲问题高精度的解答.
A parallelogram oblique element model is developed in the Finite Element Method of Lines (FEMOL) for the solutions of oblique plate bending problems. Numerical examples show that the quasi-exact results could be obtained by u-sing only a few oblique elements.
