摘要
本文利用方块脉冲函数研究一般型泛函变分的近似解法,并将其应用于求解力学中的变分问题.数值算例表明这一新的方法具有计算简便、适应性强、精度较好的优点.
Variational problem with general types of fuctional is treated by block-pulse functions in this paper.Some problems in mechanics are chosen as examples to show the validity and efficiency of this new method for providing an approxi- mate solution.
