ON THE NONLINEAR RESONANCE OF ELASTIC BEAM
Zhao Yan-Hui, Yang Pan-Chi, Qu Xiao-Gang
CHINESE JOURNAL OF COMPUTATIONAL PHYSICS    1985, 2 (3): 375-379.  
Abstract184)      PDF (270KB)(594)      
The problem of nonlinear resonance of elastic beam is studied by finite element method using a nonlinear factor. It is discovered that the resonance can also take place in this case, the resonant frequency of this problem is given. The study given here shows a new way for engineering design.
