Development of Metal Hollow Sphere Sandwich Construction and its Formability and Mechanical Property

In this paper, a new light weight construction is developed. The steel hollow sphere (MHS) sheet is sandwiched between two pure aluminum plates and the mechanical properties of the construction are investigated by means of compression test, bending test and stab-resistant test. As the results, the advanced specific stab-resistant strength and the plateau compression behaviour are found. In addition the damage progress inside of the construction is observed using a CCD camera. The fracture condition of the sandwiched MHS are compared with that of a conventional foam metal sandwich construction. The formability of the plate and energy absorption property are measured and the optimal construction condition is discussed.
