WebAug 7, 2024 · Here, the Chamis model is adopted to validate the elastic parameters obtained for yarns, as it was widely used for the prediction of yarns’ properties. Besides, the equations will be used to predict the equivalent properties of damaged microscale RVE, because it can be implemented in the multiscale framework easily. WebChamis model predicts the trends of failure modes relatively well, but the predicted strengths are quite different from experimental data. This difference is mainly because Chamis model does not consider stress concentration effect around a hole. The hole notch effect on stress concentration can be measured using factor of rupture[3].
