THE STRESS STATE IN A MOVING ROD SUDDENLY ELASTICALLY FIXED AT ITS TRAILING END

The stress and deformation states are investigated in a cylindrical el astic rod which has been moving with a constant initial velocity nu(O) in its longitudinal direction before being suddenly elastically fixed at its trailing end. A stress amplifying factor is evaluated dependin g on the stiffness of the fixation and the rod showing that the maximu m stress in the rod may be increased significantly by an elastic fixat ion in comparison to a rigid blocking of the trailing end.
