Effect of Friction on Compression Test of Ti-6Al-4V with Open-Cellular Structure

Abstract:

The compression test data are represented for a cellular Ti-6Al-4V titanium alloy, manufactured using laser powder bed fusion on EOSINT 280. The inhomogeneity of deformation was revealed in the form of a barrel of the side surfaces during the test. The problem was simulated by the finite element method for two formulations: the compression of cellular material with friction and without friction. A comparison of the stress-strain state of the two cases was made. The same inhomogeneity of deformation is achieved, both in the experiment and in the analytical solution.
