BUCKDEL v 0.9 Users and Theory Manuals: Buckling and Delamination Analysis of Stiffened Laminated Plates.

Abstract

BUCKDEL, performs geometrically nonlinear analysis of stiffened laminated composite plates with and without delaminations. BUCKDEL allows the user to perform: a linear static solution; a linear buckling (eigenvalue) analysis; and a nonlinear post-buckling analysis through both limit and bifurcation points. There are two finite elements in BUCKDEL; a quasi-conforming triangular laminated plate element based on a refined first order shear theory with seven degrees of freedom per node and a fiber reinforced beam element with seven degrees of freedom per node. The behavior of all materials is assumed to be linearly elastic. The multi-domain modeling method is used for the analysis of laminated plates containing delaminations. In this model, the delaminate, base and the undelaminate are modeled as 3 distinct. On the delamination front, Mindlin's deformation assumption is applied to obtain the relationship between the displacements in the delaminate, base and undelaminate.
