Description
Summary:Structural defects alter the dynamic characteristics of mechanical structure. They reduce the service life of mechanical structures which may lead to catastrophic failure. These defects are characterized by changes in their eigen-parameters. Thus, detection of defect using reliable and effective method is an important consideration to guarantee the component safety and prolong the service life of the structure and hence save costs. This paper discusses the effect of variations in the dynamic properties with respect to the present of a single progressive crack in beam with special considerations on free-free end condition using operational modal analysis. The validity of the results is verified with the well-established experimental modal analysis. ©2010 Society for Experimental Mechanics Inc.
