Sensitivity-based virtual fields for the non-linear virtual fields method. [PDF]
Comput Mech, 2017 The virtual fields method is an approach to inversely identify material parameters using full-field deformation data. In this manuscript, a new set of automatically-defined virtual fields for non-linear constitutive models has been proposed.

Identification of the plastic zone using digital image correlation [PDF]
Fracture and Structural Integrity, 2014 In this paper Digital Image Correlation (DIC) is used to study the evolution of the plastic zone close to a crack tip. A modified CT-specimen was used in order to fulfill the plane stress condition.
