An anisotropic, brittle damage model for finite strains with a generic damage tensor regularization
This paper establishes a generic framework for the nonlocal modeling of anisotropic damage at finite strains. By the combination of two recent works, the new framework allows for the flexible incorporation of different established hyperelastic finite strain material formulations into anisotropic damage whilst ensuring mesh-independent results by employing a generic set of micromorphic gradient-extensions. First, the anisotropic damage model, generally satisfying the damage growth criterion, is investigated for the specific choice of a neo-Hookean material on a single element. Next, the model is applied with different gradient-extensions in structural simulations of an asymmetrically notched specimen to identify an efficient choice in the form of a volumetric–deviatoric regularization. Thereafter, the generic framework, which is without loss of generality here specified for a neo-Hookean material with a volumetric–deviatoric gradient-extension, successfully serves for the complex simulation of a pressure-loaded rotor blade. The codes of the material subroutines are accessible to the public at https://doi.org/10.5281/zenodo.11171630 .
期刊介绍:
Featuring original, peer-reviewed papers by leading specialists from around the world, the International Journal of Damage Mechanics covers new developments in the science and engineering of fracture and damage mechanics.
Devoted to the prompt publication of original papers reporting the results of experimental or theoretical work on any aspect of research in the mechanics of fracture and damage assessment, the journal provides an effective mechanism to disseminate information not only within the research community but also between the reseach laboratory and industrial design department.
The journal also promotes and contributes to development of the concept of damage mechanics. This journal is a member of the Committee on Publication Ethics (COPE).
