On numerical moment-curvature relationship of a beam

A mechanics model in design of flexible nozzle with multiple movable hinge boundaries

“…For traditional problems of large deformation of elastic beam [ 22 ], the loads are not complicated, e.g., dead load [ 23 ] and follower load [ 24 ]. The former one is constant in magnitude and direction [ 25 , 26 ]. The latter one is variational followed with deformed beam, generally the magnitude is unchanged but the direction keeps consistent with beam during deformation [ 27 ].…”
