N2 - A hybrid glass/aluminum/titanium fiber metal laminate (FML) based on the standard GLARE concept was proposed in present paper, and its notched behavior was investigated experimentally and numerically. Experimental results revealed that a special three-stage stress-stain curve was obtained by this reinforced GLARE, which was related to the transition of load bearing mechanism. As well as, improvements of notched strength and normalized notched strength were achieved benefiting from the high strength and ductile nature of titanium, where their maximum increments obtained at D/W=0.2 were 11.88% and 15.40%, respectively. In addition, numerical results indicated that the finite element model (FEM) predicted well the notched behavior of GLARE with incorporating the thermal residual stress effect. Moreover, the comparisons of internal energy and damage dissipation energy between standard GLARE and reinforced GLARE have facilitated in the understanding of reinforced effect of titanium. It is believed that the present investigation can provide some useful information for damage tolerance design of FMLs.
