THE VIBRATIONS AND STABILITY OF BARS WITH PHYSICALLY NONLINEAR MATERIALS

Abstract

In the article, the methods of vibrations and dynamic stability analysis of bars having the nonlinear diagram deformation of material are suggested. The example of calculation of a bar with hinged supports of ends is given. The graphs of bar deflection as a function of time parameter are constructed.
