DOI: 10.1007/s10237-016-0858-2
Abstract: We aimed to verify a custom virtual fields method (VFM) to estimate the patient-specific biomechanical properties of human optic nerve head (ONH) tissues, given their full-field deformations induced by intraocular pressure (IOP). To verify the… read more here.

DOI: 10.1007/s11340-019-00564-6
Abstract: In this study, pressure distributions were reconstructed from phase-locked surface deformation measurements on a thin plate. Slope changes on the plate surface were induced by an external flow interacting with the specimen and measured with… read more here.

DOI: 10.1016/j.ijsolstr.2021.111204
Abstract: Abstract In this study, a novel virtual fields method (VFM) based on the finite element (FE) scheme, namely FE-VFM, is proposed as an inverse method for identifying the parameters of constitutive models. In the FE-VFM,… read more here.

DOI: 10.1016/j.optlaseng.2017.11.016
Abstract: Abstract The virtual fields method (VFM) is generally used with two-dimensional digital image correlation (2D-DIC) or grid method (GM) for identifying constitutive parameters. However, when small out-of-plane translation/rotation occurs to the test specimen, 2D-DIC and… read more here.
