| Abstract |
Stability of elastic bodies and structural elements under
non-conservative loads is one of the subject areas in the mechanics
of deformable solids and stability theory which has been of
permanent interest through the entire past century [1-3].
In the literature on dynamic stability, a phenomenon called
"Ziegler's paradox" is well known. An infinitesimal viscosity in
linear non-conservative systems causes a decrease in the stability
boundary by a finite value. Similar phenomena are discussed in
detail, e.g., in the review [4]. In [5], the dynamic stability of a
beam with non-linear internal viscosity is studied. One end of the
beam is clamped, while the other end is subjected to a constant (in
magnitude) follower force. It is shown that the effect of decrease
in the stability boundary also takes place in the presence of
non-linear viscosity.
In the present paper, a free straight beam having non-linear
internal viscosity and loaded by a follower force at one end is
considered. It is shown that in this case the decrease in the
stability boundary takes place as well. |
