Buckling of Columns
Jun 17, 2014· Buckling of Columns – Euler Theory for Elastic Buckling. Buckling of Columns is a form of deformation as a result of axial- compression forces. This leads to bending of the column, due to the instability of the column. This mode of failure is quick, and hence dangerous. Length, strength and other factors determine how or if a column will buckle.
