Hello,

I have faced a problem with modeling a dynamic load.

The load is given as a displacement constraint in boundary conditions. Additionally it is connected with amplitude definition which has 20 rows in tabulated data.

The problem is that the deformed shape does not look like expected, load is an earthquake simulation (amplitudes have changing signs) and the deformation looks as it was performed only for 1st row from amplitudes. The rest is not taken into account I tried to change amplitude's time span (step, total) but it didnt work.

Hello,

I am working on my master's thesis. I have to find best fitting hyperelastic material model for simple shear test.

My task is to find most proper material model which will fit my laboratory test data. I have conducted the "single lap test" on bricks, using polymer PS.
