Verification of Checking of the Validity and Effectiveness of Damage

Journal Title: INCAS BULLETIN - Year 2017, Vol 9, Issue 2

Abstract

This paper presents a methodology for identifying some stress concentrators based on the modal analysis performed using MSC Patran and MSC Nastran programs. The influence of a beam crack on its own frequency is practically insignificant. In order to emphasize this concentrator and its position, a modal shape processing method is used, by way of a program developed in EXCEL.
