A MODEL FOR CRACK-FACE BRIDGING

A novel model for crack-face bridging is addressed. The model successfully makes analytical predictions for the compliance changes of crack-face bridging systems during crack extension as well as recutting crack-face bridges developed after crack extension. Numerical results of the model are compared with those derived from the boundary element analysis where several possible profiles of the distribution of crack-face bridging tractions are examined. An experimental application of the model to the crack-face fiber bridging of a laminal carbon-fiber/carbon-matrix composite is attempted.
