In Search of Simulating Reality: Validation and Updating of FE Models for Structural Analysis

To successfully make the move to digital prototyping, and thereby reduce the number of physical
prototypes, predictions of product performance should be provided with a measure of confidence and
validated against experimental data.
Typical applications are found in the field of modal analysis where frameworks and efficient
procedures are now available for calibrating analytical models to better correspond with the results of
experimental models .
An overview of the methodology is provided along with some examples in material identification and
FE model refinement.
