Composite Element Method for vibration analysis of structure, Part II: C-1 element (beam)

摘要

This paper is the second in a series of two devoted to a detailed study of Composite Element Method for vibration analysis of structures. The first paper focused on the principle and C-0 element of the Composite Element Method. The present one concentrates on developing the beam element of the Composite Element Method. The related contents cover the expression of displacement field, the stiffness matrix and the consistent mass matrix of beam element, and transformation matrix. Especially, the detailed numerical verifications for the beam element of Composite Element Method are presented, which involve the h-version and the c-version. Also, some applications to the vibration analyses of lathe, automobile and frame are given in detail. (C) 1998 Academic Press. [References: 5]
