... due to symmetry conditions. The process was modeled using the Aquadraw module in PAMSTAMP 2000. Sheet material properties (extradeep-drawing-quality steel, t = 1 mm, or 0.04 in.) were obtained from a tensile test. In finite-element simulation, μ = 0.15 was used, because no lubricant was used in the...

Because the indenter is pressed into the material during testing, hardness is also viewed as the ability of a material to resist compressive loads. The indenter may be spherical as in the Brinell test...
