| 1 | Dynamic Buckling of Laminated Composite Bars Subjected to Axial Impact显示文摘The impact buckling of a laminated composite bar is investigated in case of one of its endsmoving due to axial impact compression.The governing equations considering the first-order sheardeformation effect are derived by the Hamilton principle and solved by the finite difference method.Thecritical axial shortness is determined by the B-R cirterion.The given example is used to highlight the in-fluences of initial imperfection,impact velocity,stress wave and coupled stiffness.It is found that theunsymmetrically laminated bar has a quite different dynamic buckling behaviour from that of thesymmetrically laminated bar. | Wang, DY Chen, TY Xin, GN | 1998 | China Ocean Engineering1998，13，2： | 3 |
