摘要
本文提出了一种适用于直接积分法的单步误差估计、步距自适应控制算法,并用于求解弹塑性结构的动力响应。本算法可以明显地提高直接积分法的计算精度和计算的过程收敛速度。
In this paper an algorithm of error estimation of single step and adaptive step control for direct integration method is propo--sed. The algorithm is used to solve the dynamic response of elasto-plastic structures. T his algorithm can obviously enhance the calculation accuracy and convergence rate of direct integration method,
