The constrained buckling problem of geometrically imperfect beams: a mathematical approach for the determination of the critical instability points
(2015)The constrained buckling problem of geometrically imperfect beams with intermediate unilateral supports is studied in the present paper. The proposed methodology offers the ability to calculate analytically the critical ... -
