DAMAGE DIAGNOSIS OF A HINGE SUPPORT BEAM

Abstract

The incision is a model for beam damage, specifically, for an open cross crack. It is shown that one can draw a conclusion about the presence of damage flaws judging by the first natural frequency of beam flexural vibrations. The incision coordinate, its depth and length are defined by three natural frequencies of beam flexural vibrations.
