Parameter identification in elasto-plasticity: distance between parameters and impact of measurement errors
A. V. Shutov, A. A. Kaygorodtseva
A special aspect of parameter identification in finite-strain elasto-plasticity is considered. Namely, we analyze the impact of the measurement errors on the resulting set of mater…
