Size Effect on Buckling Behaviors of Gradient Elastic Slender Columns

Abstract:

For the buckling problems of slender columns, size effects on buckling behaviors have been studied based on the modified couple stress theory. The governing equations are obtained by using variational statement and the buckling loads of slender columns are assessed. The results show that the buckling loads predicted by the new model are size-dependent.
