A mixed isostatic 24 dof element for static and buckling analysis of laminated folded plates

Imperfection sensitivity analysis of laminated folded plates

“…where D e and H e are the compatibility and flexibility matrices, respectively [32]. When the assumed stress modes (shape functions) are chosen so that the stress resultants identically satisfy equilibrium equations with zero load (self-equilibrating stress field in the element), the compatibility matrix can be evaluated on the element contour Γ e , i.e., Eq.…”

Koiter Asymptotic Analysis of Thin-walled Cold-formed Steel Uprights Pallet Racks

“…The finite element analysis was carried out following [9,10] and using the finite element described in [18][19][20]. The boundary conditions for simulation of the rack were considered as pinned at one end and simply supported at the other one (see Fig.…”

Static and free vibration analyses of stiffened folded plates using a cell-based smoothed discrete shear gap method (CS-FEM-DSG3)

“…Some highlighted numerical methods that have been proposed to analyze folded plate structures are the finite strip element methods [13][14][15][16], the combined boundary elementtransfer matrix method [17], the finite element method (FEM) [3,12,[18][19][20][21][22][23][24][25][26][27][28], the mesh-free Galerkin method [2,29]. Among these methods, the FEM, which is highly appreciated by the effectiveness and the extensibility for various problems, has taken much attention from researchers.…”
