| Abstract: | Proceed form the damage mechanics, the damage propagation of SMC-R50 short-fiber reinforced composite with impact damage was analyzed, and the equation of fatigue damage rate was derived. The fatigue damage propagation of composite was tested through experiment. At same time, fatigue ilfe equation and residual fatigue life equation were given. The results Show that through testing damage propagation the fatigae falure of composite can be predected. |
