4. B modeling

4.1. Characteristics of modeling

For the 1st calculation the time step for loading discretization is \(0.1\mathrm{s}\) (■). For the 2nd calculation the time step is \(0.005\mathrm{s}\) (─), which is 20 times smaller.

Stiffnesses are variable.

4.2. Tested sizes and results

The quantities tested are the displacement coming from the load, the force existing in the discrete as well as the cumulative plasticity variable.

The figure below shows the curves from the 2 simulations. On top of these results are superimposed the curves resulting from the material parameters. The dashed discharges (- - - -) correspond to the stiffness defined in the material parameters.

The points (●) correspond to the tests carried out in the command file.
