An Analysis of Free-Vibration of Box-Beam Used the Finite Element Method |
| Abstract |
Natural phemonena and human activities such as the explosion of nuclear weapon or machinery vibration, etc. impose forces of time dependant variability on structures. In the dynamic analysis of multi degree-of-freedom system, eigenvalue problems and eigenvectors are always occured, which characterize the behaviour of vibration system.In several methods of solving eigenvalue problems, I have adopted generalized Jacobi method that Wilson had developed.In this finite element analysis, eight-node isoparametric element have been used and the condensation method was adopted. |
