Abstract

Abstract

The basic theory of unstressed state control method was addressed through introduction of the principle of co-rotational formulation. Based on the co-rotational formulation analysis, the differences of the reference frame between the traditional incremental method and the unstressed state control method were discussed, and the basic equations of the unstressed state control method were derived. The resulting formulas show that the co-rotational formulation procedure is appropriate for analysis of the basic equations of the unstressed state control method, and the derivation process has a clear mechanics concept. Moreover, case analysis demonstrates validity and advantage of the co-rotational formulation in application of the unstressed state control method.
