查询词典 formula of computation

Polar decomposition of deformation gradient in three dimensional states is often rather difficult, although it has already been solved success fully for plane problems. It is a commonly used technique to obtain the solutions through Cayley-Hamilton formula and three invariables of U. The paper introduces a nonlinear elimination method by use of orthogonal matrix's property, and gives a computation formula for polar decomposition.

It is further elaborated that the FNN with non-overlapped BPMF's has the advantage of faster on-line training which requires less computation time, but at the cost of more memory requirement to store the fuzzy rules.
