...Y. W. Kwon; C. Diaz-Colon; S. Defisher Recently, new failure criteria were proposed for brittle materials to predict their failure loads regardless of the shapes of a notch or a crack in the material. This paper is to further evaluate the failure criteria for different shapes of notches...

...Y. W. Kwon Failures of isotropic brittle materials were revisited to find out whether there are unified failure criteria, which can be applied to a load-carrying structural component made of a brittle material regardless of whether the component has a crack, a circular notch, or neither...
