The tube dimensions of nominal outer diameter were 22.02 mm (thickness 1.27 mm) and 19.05 mm (thickness 1.07 mm) and the two kinds of materials, which were mill-annealed and heat-treated alloy 600.
Two kinds of stress-strain curves are assumed for tube materials.
It is also difficult to know the accurate stress-strain curve for tube materials considered.

The need to improve the surface properties of materials, has led to the development of parts coated with hard materials deposited on substrates.
Introduction Advances in coatings, to study mono or multilayer materials and the advancement in the use of these techniques in fields as diverse as microelectronics or packaging, require the use of another test, other than traction, for to be able to characterize the mechanical properties of said coatings and of the component itself.
What has allowed, to have an alternative methodology for the determination of mechanical properties in materials, without the need for experimental tests.
Materials and Methods With the commercial software ABAQUS / CAE [3], [4] the models are generated in axisymmetric projection of the indenter-substrate assembly in order to simulate the indentation of the substrate AA Aluminum 6063 T6.
