The virtual fields method has been developed for extracting constitutive parameters from full-field measurements provided by optical non-contact techniques for instance. It is based on the principle of virtual work written with some particular virtual fields. This paper can be regarded as a general review summarising some 15 years of developments of this method. The main aspects of the method are first recalled in the case of both linear and non-linear constitutive equations. They are then illustrated by some recent relevant examples. Some studies underway as well as relevant issues to be addressed in the near future are eventually discussed.

“…Mesoscale modeling (i.e. ply-level homogeneous modeling) using continuum damage mechanics is a cost-efficient and tractable way to simulate complex damage processes in laminated composites for structural design [11] [18], which can be easily combined with continuum damage mechanics. Therefore, the present paper takes a mesoscale stand, in which intralaminar damages are modeled by continuum damage mechanics and interlaminar damages are simulated by cohesive zone models, for the development of efficient design tool of composite structures.…”

“…Regarding the continuum damage mechanics of laminated composites, Ladevèze and Le Dantec [11] constructed a continuum damage model for intralaminar mechanical behavior of laminated composite, taking stiffness reduction, fiber elastic nonlinearity, and matrix plasticity into account. This model can describe the brittle fracture of fiber, matrix microcracking and fiber/matrix interfacial debonding as damage parameters.…”

The aim of this study is to develop an appropriate modeling methodology for the simulation of intralaminar damage in laminated composites under complex loadings. The intralaminar damages are modeled by stiffness reduction controlled by thermodynamic forces as defined in continuum damage mechanics model proposed by Ladevèze. The original method neglected transverse stress in elementary plies during the tensile tests of [45/−45]mS laminates, resulting in variations of the identified damage parameters of Ladevèze model. This study compared the identified damage parameters considering transverse stress effects with those based on the original method. The effect of transverse stress in the identification process on the damage modeling is discussed, and it is found that one of damage coupling parameters and the damage master curves significantly depend on consideration of transverse stress effects. Finally, it is demonstrated that experimental stiffness degradation is well simulated by the prediction using the identified parameters considering transverse stress effects.
