The paper concentrates on discussing the distinction between UL foruulation and CR formulation in specific algorithm,and the limitation of UL formulation is pointed out.

Based on CR formulation superposition method for geometrical nonlinear analysis,the catenary cable element was used to simulate stay cable.

In this paper, we used catenary cable element imitate the cable, use the theory which is based on the CR formulation effects and considered the beam-column effect and the large displacement to establish of space model.

To improve the precision and efficiency of computations for a structure with a large displacement and rotation,an updated Lagrangian co-rotational formulation for geometrically nonlinear FE(finite element) analysis of 3-D beam elements was proposed.

A co-rotational formulation for geometrically nonlinear finite element analysis of solid is presented.

Authenticating accuracy of CR-UL formulation on geometric nonlinear analysis,and validating that there ie a Larger error on UL formulation for Calculation of geometric non-linear.

Research on CR method process of TiB_2/Al composites;

determinant method, was studied in this paper.
