FEA-Test Comparison with Modal Assurance Criterion (MAC) Analysis

The introduction of more robust computational capabilities in CAE tools over the last few decades have enabled engineers to use CAE to perform complex analysis and compare predictions with test results to strengthen their confidence in these simulated results. This evolving technology has led engineers as well as managers to challenge how they can better correlate finite element predictions (FEA) and test results to minimize the need to run costly repeated experiments. New in nCode 2019, Modal Assurance Criterion (MAC) analysis enables users to compare measured vibration mode shapes with simulated results. Attend this webinar and learn how MAC analysis is used to validate finite element models and how to correctly capture all mode shapes of interest using virtual sensors.
