New Research on Composite Engineering from D.H. Li and Co-Authors Summarized

摘要

2011 AUG 31 - (VerticalNews.com) -- "Free vibration analysis and eigenvaluesrnsensitivity analysis of composite laminates with interfacial imperfection are investigated basedrnon the radial point interpolation method (RPIM) in Hamilton system. The governing equation ofrnthe free vibration analysis and eigenvalues sensitivity analysis are both reduced by the springlayerrnmodel and modified Hellinger-Reissner (H-R) variational principle," researchers inrnTianjin, People's Republic of China report.
