AAE 352 1 Structural stability-buckling Axial compressive loads placed on structural elements such as – Columns – Plates – Shells Critical values of compression cause the structure to move sideways and carry develop bending loads – lateral (side) deflections occur - they may be large – Axial stiffness is reduced
