This work presents a combination of vibration-based method and speckle shearography in order to identify, locate and quantify the damage in composite structures. The experiments were carried out on laboratory specimens, which consist in cylinders made of carbon fiber and epoxy resin via filament winding process. Twelve composite specimens were considered in this study. Three different stacking sequence were tested: Type A [90/60/-60/90/60/-60/90] S , Type B [90/30/-30/90/30/-30/90] S and Type Cdoi:10.1016/j.proeng.2015.08.036 fatcat:smsm4mpgn5c4fevzndjfgfbdxu
