Object of interest is a steel rod with circle section. The modal parameters, such as mode shapes and natural frequencies, are obtained by two different ways: experimentally by using experimental modal analysis and numerically by finite element analysis which were computed in NX Nastran solver. The results from both methods are compared in NX through the correlation function. A relation between measured mode shapes and computed mode shapes is expressed by Modal Assurance Criterion. This process of comparing is appropriate for verification of experimental approaches. http://pubs.sciepub.com/ajme/4/7/26/ajme-4-7-26.pdf experimental modal analysis numerical modal analysis mode shape natural frequency Cross MAC
