Structural identification using a nonlinear constraint satisfaction processor with interval arithmetic and contractor programming

•A new methodology is formulated for finite element model updating.•Partially described IEP is structured as a nonlinear constraint satisfaction problem.•Measurement uncertainties are reflected in the feasible parameter space.•Feasible parameter space is completely and crisply enclosed by interval m...
