1. Reference problem

1.1. Geometry

1.2. Material properties

Isotropic elasticity	Young’s Modulus: \(E\mathrm{=}200000\mathit{MPa}\) Poisson’s Ratio: \(\nu \mathrm{=}0.3\)
Rousselier model coefficients	Initial porosity: \({f}_{0}\mathrm{=}0.01\) \(D\mathrm{=}2\) \({\sigma }_{1}\mathrm{=}500\mathit{MPa}\)
Rational traction curve	Logarithmic deformation 0.0 0.002 1.002	Rational constraint (\(\mathit{MPa}\)) 0.0 400.0 2400.0
Non-local model	Regularization of swelling: C_ GONF = 1N

1.3. Boundary conditions and loads

The bar, blocked in direction \(\mathit{Oy}\) on face \(\mathrm{[}\mathrm{1,2}\mathrm{]}\), is subject to displacement \(u(t)\) on face \(\mathrm{[}\mathrm{3,}4\mathrm{]}\).

1.4. Initial conditions

Zero stresses and deformations at \(t=0\).
