A micromechanical model for prediction of mixed mode I/II delamination of laminated composites considering fiber bridging effects

In unidirectional laminated composites, fiber bridging as a toughening mechanism has a significant effect on the behavior of mixed mode I/II delamination. In the present paper, effects of fiber bridging and related micro-mechanisms were investigated quantitatively. To this end, a novel micromechanical model called “mixed mode I/II micromechanical bridging model” was proposed based on the calculation of the delamination crack bridging zone energy...
