Mechanical buckling
WebIn the results, nonlinear buckling was found to occur as the load approached a factor of 0.89 of the full load. A second nonlinear buckling analysis was inserted into the Workbench Mechanical outline. It uses a larger factor on the UPGEOM command. This causes the buckling deformation to build up more gradually. http://www.m-isteel.com/

WebThe mechanical and thermal buckling strengths of the hat-stiffened panels with different face-sheet geometry are compared. It was found that by just microdenting or microbulging of the face sheet, the axial, shear, and thermal buckling strengths of both types of hat-stiffened panels could be enhanced considerably.
