Simultaneous identification of stiffness and damping properties of isotropic materials from forced vibrating plates

Simultaneous identification of stiffness and damping properties of isotropic materials from forced vibrating plates
Simultaneous identification of stiffness and damping properties of isotropic materials from forced vibrating plates
This paper presents a novel methodology for the identification of damping of isotropic plates. It relies on forced inertial excitation of a clamped plate and full-field curvature measurements using a suitable optical technique. Using the Virtual Fields Method, it is shown that the damping parameter is easily related to the curvature field, even on a non-resonant plate. This paper opens a totally new field of investigation for damping identification

Abstract

This paper presents a novel methodology for the identification of damping of isotropic plates. It relies on forced inertial excitation of a clamped plate and full-field curvature measurements using a suitable optical technique. Using the Virtual Fields Method, it is shown that the damping parameter is easily related to the curvature field, even on a non-resonant plate. This paper opens a totally new field of investigation for damping identification
