Calibration of constitutive models with error control

• In this thesis a framework for the calibration ofconstitutive models is presented. The framework involves theformulation of an optimization problem which is solved usingstrategies based on, essentially, Newton's method. The introductionof an additional costate field in order to incorporate the stateequation has the advantage that error control in an arbitrary "goal"quantity is formally straightforward. The errors analyzed are thosethat arise from the Finite Element discretization and fromuncertainties in the experimental data. Among the applications,moisture transport in wood and nonlinear viscoelasticity arediscussed in more detail.
