Effect of moisture on the delamination properties of fractured PVB-laminated glass: A joint experimental and numerical study

•The effect of moisture on the delamination properties of PVB-laminated glass is characterized by TCT tests and a numerical cohesive zone model.•Four initial moisture levels, i.e., 0.2%, 0.4%, 0.6% and 0.8%, are considered.•The cohesive strength and interfacial fracture energy decrease by 70% and 50%, respectively, as the moisture content increases from 0.2% to 0.8%.•The energy absorption of fractured PVB-laminated glass decreases significantly with increasing moisture content due to material degradation and reduced interfacial adhesion.
