| Abstract: | On basis of Mindlin first order shear effect plate theory, an incremental element formulation of the stiffened laminated plate is deduced. The temperature dependent thermal and mechanical properties of composite are considered. A study of thermal nonlinear buckling behavior for the stiffened laminated plate with a delamination damage under temperature enviroment is presented. Numerical results and discussions of some typical examples show that the effects of thermal and mechanical properties with varying temperature, areas and locations of the delamination on the buckling characteristic and mode are significant. |
