Abstract

This paper discusses on a full and large field, high spatial resolution, contact-less, and non-intrusive approach for force retrieval at different excitation regimes of mechanical structures. The inverse problem based on the Force Analysis Technique is combined with the full-field measurement to identify the force applied to a structure, in terms of localization and quantification. In the transient regime, the proposed approach is able to retrieve the time dependence of the force and yields good agreement with that from a piezoelectric force sensor.
