Static repair of multiple cracked beam using piezoelectric patches

This paper addresses the problem of repairing multiple cracked beams subjected to static load using piezoelectric patches. First, is formulated and solved analytically for case two cracks that results in ratio restoring moments produced by employed Since dependent only on crack positions but not their depth, result obtained has been extended cracks. proposition then validated finite element simulation where patches are replaced mechanical moment equivalent bending The excellent agreement between analytical solution numerical single double allows making a conclusion patch could productively repair beam producing due its piezoelectricity. Thus, solved.
