Modeling \(\mathrm{2D}\) : 1 quadrangle QUAD8

The imposed load is as follows:

the nodes \(\mathit{N1}\), \(\mathrm{N5}\) and \(\mathrm{N2}\) are blocked in the direction \(y\),
node \(\mathrm{N1}\) is locked in the direction \(x\),
the nodes \(\mathrm{N4}\), \(\mathrm{N7}\) and \(\mathrm{N3}\) are displaced by \(\mathrm{1.5mm}\) in \(\mathrm{1.5s}\) spread over 50 increments.

The values are calculated at Gauss points.

At calculation time \(t\mathrm{=}0.93s\), we find for both models:

For the local version of the Rousselier model:

For the Rousselier model in a non-local version:

At the final moment \(t\mathrm{=}1.5s\), we find for the gradient model:
