A quantitative assessment of random field models in finite element buckling analyses of composite cylinders

, 2012
Large scatter characterizes the collapse load of thin-walled structures due to their imperfection sensitivity. Random fields can be used to include imperfections in a finite element model.

Parametric study on average stress-average strain curve of composite stiffened plates using progressive failure method

Latin American Journal of Solids and Structures
The post-buckling behavior of composite ships' stiffened plate panels has been studied. In this study, the average strain- average stress curves for these panels are derived using progressive failure method as well as nonlinear finite element method. The

On the structural design of imperfection sensitive laminated composite shell structures subjected to axial compression [PDF]

, 2016
Shell structures are used as primary structures of space launch vehicles. These structures are thin-walled and are thus prone to buckling when loaded in compression.
