DYNAMIC FORMS OF LOSS OF STABILITY OF AN ELASTIC SYSTEM
Abstract
A study is made of the dynamic behavior of fundamental forms which have been subjected to compression. It is determined that for loads exceeding the initial critical values suddenly applied to an elastic system, there results a motion after which the system does not return to its original state. If this function is harmonic the motion is a normal oscillation. Examples of these determinations are presented.

The problem of motion of a solid body floating on the surface of an incompressible liquid or on the surface of a liquid partly filling a shell is considered as a problem of hydrodynamic impact of a solid body against an incompres ible liquid in those cases, in which this motion undergoes very high accelerations within a sufficiently short period of time. The investigation of horizontal impact is much more complicated than that of a vertical impact because the latter comes to the problem of a smooth flowing around a body entirely enveloped by a liquid. The simplest case of a three-dimensional horizontal impact, i.e., when the solid body is a sphere half immersed in a noncompressible liquid or a spherical shell half-filled with liquid is investigated.
