In this study, we proposed both a numerical and experimental methodology for material parameter identification to validate the gradient‐damage model in . A nonlocal anisotropic damage model for viscoplastic thin‐walled shells was proposed by introducing a gradient‐enhanced free energy function. For the experimental methodology, cyclic micro‐bending and ‐tensile tests were conducted to identify the damage size effects to calibrate the proposed FE model. Numerical results were obtained and compared with displacement‐force curves from shock‐tube tests. (© 2017 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
