buckling factor as low as 0.05

buckling factor as low as 0.05

hi everyone,

I carried out a linear buckling analysis of a skin panel using nastran solver 105. The loads were applied as enforced displacement form a global model. surprisingly first mode buckling factor was 0.06365. Iam quite sure that the panel will not buckle at the applied load times the buckling factor. Its a very less load. A simple hand calculations gives a reasonably justifiable critical buckling stress. What could the possible reasons for a very low buckling factor ? Thanks in advance.
