Parametric Correction of Finite Element Models

Summaty This paper concerns the computational aspects of a the new correction method for the control and the refinement of a given finite element model using modal tests results, when finite element models represent complex structures. The updating strategy is iterative and each iteration is divided into two stages : first, the local error measure on the constitutive relation is used to locate the most erroneous areas, second, the mass and stiffness matrices are corrected. Some examples illustrate this strategy.
