As a consequence, they are extensively used for highly<br />demanding applications, such as cutting and drilling tools, where cyclic loading is one of the most<br />critical service conditions.<br />A numerical study of the mesoscale fatigue crack growth in WC-Co is here conducted. Within this<br />context, a model based on a continuum damage mechanics approach was implemented in<br />commercial solver Abaqus/Explicit for simulating the crack propagation in the material. Separate<br />damage laws, based on brittle failure and fatigue, were used for describing the mechanical<br />response of WC and Co phases, respectively. Material parameters for the carbide phase were<br />taken from literature, whereas those for the metallic phase were experimentally determined in a<br />model binder-like Co-base alloy, i.e. one with a composition representative of the binder phase<br />within a commercial hardmetal grade.<br />In order to validate the approach used, a numerical model based on a real damaged microstructure<br />was generated. It is found that proposed model is capable of capturing damage evolution with<br />cyclic loading in WC-Co, as numerical results reflect satisfactory agreement with real crack pattern<br />resulting from experiments.}, journal={International Conference on Stone and Concrete Machining (ICSCM)}, author={Özden, Utku Ahmet and Jiang, Keng and Bezold, Alexander and Broeckmann, Christoph and Tarragó, Jose María and Mestra, Alvaro and Llanes, Luis}, year={2015}, month={Nov.}, pages={9–20} }
