Goal-oriented model calibration using the adjoint framework

Abstract : We define and analyze a goal-oriented procedure for model calibration in Computational Mechanics. In this procedure, priority is given in the updating to parameters which are the most influent to predict a given quantity of interest. The strategy uses the constitutive relation error framework as well as duality and adjoint techniques. The objective is thus to perform a partial model validation that enables to obtain the value of the quantity of interest with sufficient accuracy and minimal modeling effort.
