A multi-stage material model calibration procedure for enhancing numerical solution fidelity in the case of impact loading of composites

The numerical prediction of impact-induced damage to composite materials and the subsequent residual strength under compression loading continue to be a challenging task. The current study proposes a calibration routine for optimizing the set of material model parameters prior to the virtual simulation of impact tests, which also simplifies the process of parameter determination. The calibration algorithm is based on the comparison of the...
