Study of Formability of Sandwich Shells with Metal Foam Cores Based on Punch Penetration Test

Abstract:

The objective of this work is the study of the mechanical behaviour of a sandwich structure, composed by two out layers in aluminium sheets, separated by a core in metal foam also in aluminium, by penetration of a spherical punch. Considering a structure composed by these two different materials, each one presents a different mechanical behaviour separately [1, 2].The set up used in the present experimental work is composed by a punch, with a radius r, which imposes a displacement/force to a specimen fixed in its boundary.In these tests, specimens with four different length were considered; 25 mm, 50 mm, 75 mm and 150 mm. The values of force/displacement of the punch were registered.
