摘要
Abstract
A concept of the flow function and the corresponding variational principle were developed to deal with the absolute incompressible material system, and the numerical analysis was also presented. When the flow function was introduced, the higher order differential system was involved, which led to a new type of element, the inter-belt finite element, based on the belt theory. The belt finite element can overcome well the problem derived by the variational principle with the higher order differential.关键词
