Abstract

- A recently proposed technique for the calibration of constitutive models is based on the optimization problem expressed such that the state equation is incorporated via an additional costate field. A distinct advantage is that error control is formally straightforward. This technique is applied to calibration of a nonlinear elastic composite using a meso-macro-transition approach, whereby the RVE is analyzed using (in this case) Dirichlet boundary conditions. The numerical results show the effectivity of the error prediction.
