摩擦接触问题数学规划法的收敛性和算法的改进
Convergence analysis of the mathematical programming methodfor solving frictional contact problems and an improved algorithm
【摘要】 对摩擦接触问题的数学规划法进行了收敛性分析,并对算法提出一种改进,对“较小”摩擦系数问题改进算法严格保证收敛。在“较大”摩擦系数情形,问题提法本身有可能发生解不唯一和不存在现象。
【Abstract】 The convergence analysis for the mathematical programming method to frictional con-tact problems and an improved algorithm is presented and it is proved that the improved al-gorithm is successful for the problems with “relative small” friction coefficients.For“rela-tive large”friction coefficients nonuniqueness and nonexistence of solutions are real possibli-ties.
