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

作者：

Highlights：

• CS-FEM-DSG3 is extended for static and free vibration analyses of stiffened folded plates.

• Original CS-FEM-DSG3 is combined with an Allman's plane stress triangular element and stiffened by Timoshenko beam element.

• Stiffeners can be placed anywhere on the plate and need not be placed along the mesh lines.
