Identification of the local stiffness reduction of a damaged composite plate using the virtual fields method

In the present study, a damage detection problem is formulated as the identiﬁcation of the spatial stiﬀness distribution in a damaged composite plate. Full-ﬁeld heterogeneous curvature ﬁelds obtained from an optical deﬂectometry technique are processed by using the virtual ﬁelds method adapted to...
