Stability analysis of helical rod based on exact Cosserat model被引量:1
《Applied Mathematics and Mechanics(English Edition)》2011年第5期603-612,共10页刘延柱 薛纭

Helical equilibrium of a thin elastic rod has practical backgrounds, such as DNA, fiber, sub-ocean cable, and oil-well drill string. Kirchhoff's kinetic analogy is an effective approach to the stability analysis of e...

Variational principle for a special Cosserat rod
《Applied Mathematics and Mechanics(English Edition)》2009年第9期1169-1176,共8页刘东生 Charles H-T WANG 
supported by the Scientific Research Foundation for the Returned Overseas Chinese Scholars,State Education Ministry of China
In this paper, we describe the nonlinear models of a rod in three-dimensional space based on the Cosserat theory. Using the pseudo-rigid body method and variational principle, we obtain the motion equations of a Cosse...
