Buckling and postbuckling behavior of composite laminates with a delamination
Composites Science and Technology, 1997A finite-element model is presented for studying the buckling and postbuckling behavior of composite laminates with an embedded delamination. Degenerated-shell elements and rigid-beam elements are utilized for the finite-element model. In the non-linear finite-element formulation, the updated Lagrangian description method based on the second Piola ...

Buckling and postbuckling of composite beams in hygrothermal environments
Composite Structures, 2016Abstract This paper presents an investigation into the buckling and postbuckling of composite beams in hydrothermal environments. The free expansion due to both temperature variation and moisture absorption has been taken into consideration. In the meantime, the material properties are considered to be temperature- and moisture-dependent.

Buckling and postbuckling behavior of delaminated composite struts
International Journal for Computational Methods in Engineering Science and Mechanics, 2017ABSTRACTThe buckling and postbuckling behavior of composite struts under uniaxial compression is investigated. A geometrically nonlinear model comprising only four generalized coordinates is applied to multi-layered struts built up of transversally isotropic unidirectional layers. Laminates with a cross-ply layup are investigated.
