Buckling or structural instability is a common failure in mechanical, aerospace and civil
structures under compressive loads. Any aerospace or mechanical structure subjected to
axial compressive load is assumed as column. Therefore, excellent knowledge on buckling
behaviour of columns is necessary as an airframe is constructed of long slender plates and
stiffeners, of which half will experience a compressive load leading structure instability if
overloaded. The present study estimates the failure load of columns under axial …
