Numerical and experimental study of the bulge test of sandwich shells with metal foam cores
Abstract
The Hydroforming process can be defining as a tradition forming process with the difference that instead of using a punch to stamp the piece into shape, the punch is directly acted upon by fluid pressure (water, hydraulic oil, emulsion). A typical cycle includes placing the blank inside a die, closing it, and applying pressure to one side of the sheet. The powerful pressure exerted presses the blank against the wall of the die to yield the desired shape. In the study design process of forming the bulge test are current used. Very similar to hydroforming process in this test the material is submitted to a variable pressure in the center of one side of the specimen, whit the border fixed. Traditionally this test was used to study the behavior of sheets. The present investigation was used to evaluate a composite structure in aluminum composed by to out layers in sheet and metal foam core. The type of material to forming is the fundamental aspect is in this work, because the sandwich panel's combines two different materials, with two different functions in that composite structure and the function of the composite when are applied in a global structure cannot fail by the interference of the process of forming [1, 2]. In this work a procedure able to forming this composite which does not affect the role of the two materials of the panels was analyzed. Bulge test was performed to evaluate experimentally the formability of this composite. The experimental results are also compared with numerical simulation developed, considering in these simulations the anisotropy of the aluminum sheet and the influence of this in the formability in the global structure during the hydroforming process.
