DQ-SEMIANALYTICAL METHOD WITH TIME POINTS FOR STRUCTURE DYNAMIC ANALYSIS
Peng Jianshe, Zhang Jingyu, Yang Jie
CHINESE JOURNAL OF COMPUTATIONAL PHYSICS    1998, 15 (2): 239-243.  
Abstract280)      PDF (176KB)(1030)      
A method is proposed for controlling partial differential equation directly to beam.It takes differential quadrature method in space domain and series in time domain,and yields equations of determining all parameters for the displacement field by adding time points.The response displacement field can be obtained by solving linear equations.
