| Title |
A multifrequency model of rod buckling under creep conditions |

| Abstract |
A scleronomous rod with a nonlinear characteristic was studied in [1] with
the use of a perfect I-beam scheme on the basis of a representation of the
desired deflection by a series with bounded number of terms. The method
developed in [1] was used in [2] to determine the critical time typical of
a rheonomic rod. In the present paper, to solve the buckling problem, we
propose a new mathematical model based on the pure buckling scheme [3].
We establish an analogy concerning the results of solution of three
deformation problems for a hinged rod: creep buckling, stability, and
transverse vibrations within the elastic range. In the study of a
two-frequency model with two functions of time, we also find an integrating
factor, which allows us to relate the amplitudes of the first and second
harmonics and analytically show that the first harmonic dominates. |
