Dynamic Stability of Suddenly Loaded Structures

Abstract

Dynamic stability is defined and classified, and examples are given for the various classes of problems. Criteria are developed for practical stability and it is shown that in a paractical elastic column tested in a conventional testing machine stress reversal always precedes the attainment of the maximum load. The two coincide, however, in the limit when the initial deviations of the column axis from straightness and the loading speed tend to zero.
