Publication: A global equilibrium method accepted in "Computers and Structures"

14 January, 2011

New identification strategies have to be developed on order to perform the identification quickly and at very-low cost. A popular class of approaches relies on full-field measurement obtained through  digital image correlation. We propose here a Global Equilibrium Approach. It is based on the virtual field method in case specific virtual fields are used. It can also be seen as a generalization of the equilibrium gap method. This approach is easy to implement and we prove it provides better or comparable results to the constitutive equation gap method that is known to be a very accurate reference.
