The virtual fields method with piecewise virtual fields

International Journal of Mechanical Sciences, 2006
This paper deals with the identification of constitutive parameters of materials from whole-field strain data. The inverse identification procedure used is the virtual fields method. It is based on the principle of virtual work written with particular virtual fields.

Sensitivity of the virtual fields method to noisy data

Computational Mechanics, 2004
This paper deals with the application of the virtual fields method (VFM) to the identification of constants governing anisotropic constitutive equations. After a short recalling of the main features of the VFM, its sensitivity to noisy data is addressed.

Special virtual fields for the direct determination of material parameters with the virtual fields method. 1––Principle and definition

International Journal of Solids and Structures, 2002
This paper deals with the direct and simultaneous estimation of parameters used in some constitutive laws. Whole-field data captured in mechanical configurations which give rise to heterogeneous stress fields are processed. Since no analytical relationship is available between measured data and unknown parameters, a specific procedure based on a ...

The Virtual Fields Method

2012
The Virtual Fields Method (VFM) is one of the techniques developed to identify the parameters governing constitutive equations, the experimental data processed for this purpose being displacement or strain fields. It will be shown in this chapter that one of its main advantages is the fact that, in several cases, the sought parameters can be directly ...

Software Implementation of the Virtual Fields Method

Applied Mechanics and Materials, 2007
The virtual fields method is a tool dedicated to the identification of the mechanical properties of materials from full-field deformation measurements. It is now validated in elasticity and plasticity but one of the remaining problems is the fact that researchers wanting to use the method must invest significant time in order to programme the routines.

Three-Dimensional Virtual Intraoperative Reconstruction: A Novel Method to Explore a Virtual Neurosurgical Field

World Neurosurgery, 2020
Acquisition of neurosurgical anatomy knowledge requires the progressive construction of a 3-dimensional (3D) mental image from the study of 2-dimensional pictures. Tridimensional neuroimaging modeling and 3D pictures and videos have facilitated a better understanding of intricate brain anatomy.
