3. Modeling A#
3.1. Characteristics of modeling#
Material point, behavior VISC_MEMO_NRAD.
Each elementary cycle (a traction-compression for a given twist) is discretized in 48 steps. To perform a complete turn on the previous diagram you need \(360\mathrm{/}15\mathrm{=}24\) elementary cycles.
We complete 4 full laps in total, for a total of \(48\mathrm{\times }24\mathrm{\times }4\mathrm{=}4608\) time steps.
3.2. Tested sizes and results#
The representation of the results in a \(\sqrt{3}{\sigma }_{\mathit{xy}};{\sigma }_{\mathit{xx}}\) diagram shows the stabilization of the response
The extreme stress values obtained at the end of loading are
