“…Great attention had also been paid to the mechanical properties of honeycombs when subjected to different types of external loading, including in-plane tension [100], in-plane biaxial compression, out-of-plane transverse shear [101,102], peel [103], uniaxial tension [104], three-and four-point bending [105], combined in-plane compression and shear [106], combined out-of-plane compression and shear [93], creep [107], fatigue [108], dynamic shear and, recently, low-and high-velocity impact [109,110]. Generally, deformation of honeycombs under these loadings can be interpreted by combining three different modes: flexing, stretching and hinging [111].…”
