%X The buckling of an axially compressive strut constrained by a flexible sleeve is studied for the cases of a single point contact and a curved line contact between the strut and the sleeve.Under the small deflection assumption,the second order differential equilibrium equations of the strut and the sleeve satisfying deformation compatibility conditions are obtained.The deflection,the axial displacement,and the contact reactions of the strut are then obtained.The length of the line contact is uniquely determined by the axially compressive force. Two examples indicate that the axial displacement of the strut caused by bending is large when the stiffness of the sleeve is small,and vice versa,which is in good agreement with the large deflection solution.It is confirmed that the small deflection assumption is valid here.
