I started by replicating a uniaxial compression test of a cylindrical specimen (6mm high by 12mm diameter) which is crushed between two 1mm plates. Knowing E=50MPa, the area of \u200b\u200bthe specimen, the crushing and the initial height, I was able to calculate the constraint reaction that I would have to measure in the lower constrained plate.<br \/>Having clearly understood that the result (measured with a probe) would give variable results with the density of the mesh, I did more tests by increasing the latter. However, what happened is that as the mesh thickened the measured force grew until it stabilized at a value of 1388N against the target 942N,&nbsp;when instead I would have expected the opposite, as the mesh increased I should have approached the &#8220;real&#8221; value and not the opposite.<br \/>Thank anyone who can help me, obviously i will provide all the test setup.
