Traditional sandwich structure consists of two face sheets and a core. With an internalsheet inserted into the core, a two-core sandwich structure is then formed. Two-core sandwichstructures with composite laminated face sheets and a thin internal sheet subjected to low velocityimpact are studied in this paper. Local displacement of the core under the point of impact isinvestigated. Simulated results show that the local displacement of the core along the direction ofthe impact has been decreased significantly by introducing the internal sheet into a traditional singlesandwich structure and by reducing the space between the internal sheet and the impacted face sheet.Shear deformation in the cores of a two-core sandwich structure is also investigated and attention isfocused on shear strains on interfaces between face/internal sheets and the cores. Results furthershow that strain levels in selected elements at the interested interfaces depend upon locations of theselected elements and arrangements of the internal sheet
