Supplementary data for "A constitutive model of porous polycrystals viscoplasticity."

Description We are releasing the codes, datasets, and results as the supplementary information for our manuscript “Revisiting snow settlement with microstructural knowledge”. 1 Software and code: The code, Amitex FFTP, used to generate the results exposed in this paper is freely available at the address: . Examples of use are given on the same site. The behaviour laws are generated with the Mfront software, available at: tfel An example of input data for a viscoplastic simulation of porous ice using AMITEX is available at: Zenodo repository porous polycrystals. 2. Microstructure-based simulations: For each type of pores ('polyhedral, spherical and interstitial) the numerical results are included in a single file 'geo_properties_simulations_{polyhedral; spherical; interstitial}.csv'. These files contain the geometric properties, the identified material parameters and the macroscopic responses to uniaxial loading (strain-rate and stress). Specifically: Column 1: Solid fraction (’phi’) ranging from 0 to 1; Column 2: Coordination ratio (’Z’); Column 3: Surface ratio (’r’); Column 4: Contiguity (’beta’) ranging from 0 to 1; Column 5: Stress exponent (’n’); Column 6: Reference stress (’s0 (MPa)’); Column 7: Viscous Poisson ratio (’nu_v’); Columns 8-13: Mean strain rates in xx, yy, zz, xy, xz, and yz for loading ˙ϵzz = 1 × 10−5 s−1 (’depsii 1e-5’); Columns 14-19: Mean strain rates in xx, yy, zz, xy, xz, and yz for loading ˙ϵzz = 1 × 10−6 s−1 (’depsii 1e-6’); Columns 20-25: Mean strain rates in xx, yy, zz, xy, xz, and yz for loading ˙ϵzz = 1 × 10−7 s−1 (’depsii 1e-7’); Columns 26-31: Mean stresses in xx, yy, zz, xy, xz, and yz for loading ˙ϵzz = 1 × 10−5 s−1 (’sii 1e-5 (MPa)’); Columns 32-37: Mean stresses in xx, yy, zz, xy, xz, and yz for loading ˙ϵzz = 1 × 10−6 s−1 (’sii 1e-6 (MPa)’); Columns 38-73: Mean stresses in xx, yy, zz, xy, xz, and yz for loading ˙ϵzz = 1 × 10−7 s−1 (’sii 1e-7 (MPa)’);
