Study of Finite Substructural Method in Contact Problems of Concrete

针对接触问题的求解是一个反复迭代过程,提出减少每次迭代过程中方程的数目接触问题的求解效率将得到很大提高,借助子结构技术可方便实现减少每次迭代过程中方程的数目。通过工程算例对比,结果表明子结构技术在混凝土接触应力计算中具有优势,提高了有限元计算效率。

The solution for contact problems is the course of repeated iteration. Solution efficiency has produced noteworthy results if numbers of equations can be reduced by using the substructure method in each iteration. Comparision between numerical simulation methods shows the effectiveness of the finite substructure method.
