An Anisotropic Continuum Damage Mechanics Model for the Simulation of Yield Surface Evolution and Ratcheting

    https://doi.org/10.1142/S1758825122500442Cited by:1 (Source: Crossref)

    A new anisotropic continuum damage model was presented on the basis of irreversible thermodynamics. Second rank symmetric damage tensor, kinematic hardening tensor, and damage potential surface were introduced. The yield surface in this study has been modeled to distort in the stress space by the evolution of the damage tensor. The new model was applied in yield surface characterization and led to a well description of the subsequent yield surfaces. This model is then applied to predict experimental results of the cyclic nonproportional loading paths obtained by Kang et al. [2004], Hassan et al. [2002] and Taleb and Cailletaud [2011]. It is demonstrated that the new model can predict the yield surface distortion and the ratcheting strains of multiaxial nonproportional cyclic loading with acceptable accuracy and by using less material constants with respect to the previous models.

    Publisher's Note:

    In the earlier version, the numbering "Fig. 9" was used twice, for two different figures, causing ambiguity in their citations. The second "Fig. 9" has been corrected to "Fig. 10", and all figure numberings onwards and their in-text citations are adjusted accordingly. This information has been updated on 30th August 2022.
