2. Modeling A#
2.1. Characteristics of modeling#
Modeling A is done in sub-integrated 3D (3D_ HM_SI), using STAT_NON_LINE.
The time step is from \(\mathrm{\Delta }t=\mathrm{0,4}\mathit{sec}\) to \(t=\mathrm{9,6}\mathit{sec}\) (purely elastic phase), then from \(\mathrm{\Delta }t=\mathrm{0,025}\mathit{sec}\) to \(t=12\mathit{sec}\) (plastic phase). The automatic redistribution of the time step is activated.
2.2. Tested sizes and results#
2.2.1. Tested values#
The solutions are calculated at point:math: C and compared to the solution given by SIMU_POINT_MAT at the final time:math: t=12mathit {sec} `. They are given in terms of effective horizontal stress:math: `{mathrm {sigma}} _ {mathit {xx}}}, hydraulic pressure:math: p, as well as those of plastic volume deformation:math: math: math: {mathrm {epsilon}}} _ {v} ^ {p} and plastic deviatoric deformation:math: `| {mathrm {epsilon}} _ {d} ^ {p} |=sqrt {frac {3} {2}left (mathrm {epsilon} -frac {{mathrm {mathrm {epsilon}}} _ {v} ^ {p}}} {3} Iright)mathrm {:}left (mathron}} m {epsilon} -frac {{mathrm {mathrm {epsilon}}} _ {v} ^ {p}} {3} Iright)} `, and summarized in the following table:
