Abstract

The stress distribution on the failure progress of fiber pushed-out test was studied. A numerical program, developed by meso-damage mechanics, was adopted to simulate the whole failure process of interface debonding and fiber pushing out. From the simulation, it can be concluded that, the interfacial stress on load side and support side is larger than other portions. Simultaneously, the shear stress in both sides becomes larger when thickness of sample reduces. Furthermore, when the diameter of fiber increases, the shear stress on load side is getting larger but in support side it is diminishing. On the other hand, changes of the support hole’s diameter only affect the interfacial shear stress on the support side.
