Mode II interfacial fracture characterization of foam core sandwich materials at elevated temperatures: the effects of frictional stresses between the crack edges

In recent years, composite sandwich material has been widely used in civil engineering due to its high strength to weight ratio, high stiffness to weight ratio and anti-corrosion ability. However, the existing research studies indicated that interfacial delamination between skins and core was a common failure mode for this kind of material, which seriously threatens the durability and safety of structures. Furthermore, up to now, there are no...
