-
摘要: 接触问题是一个多重非线性问题,难以转化为经典的光滑模型进行求解,运用非光滑分析的理论与算法研究有摩擦的接触问题,给出了二维摩擦接触问题的一种非光滑方程组模型及算法,并给出了算例.该算法未引入任何人工变量,列式简单,计算量小,实际算例及随机算例也表明了算法的有效性.Abstract: Problems of frictional contact, viz., a nonsmooth equations model and its nonsmooth method for two-dimensional frictional contact problems are studied. The method does not need any extra variables, is simple in its formulation, and reduces much computational time. An example and some random examples show the efficiency of this method.
