Lucarini, M.A. Moreno-Mateos, K. Danas, D. Garcia-Gonzalez. Insights into the viscohyperelastic response of soft magnetorheological elastomers: competition of macrostructural versus microstructural players. International Journal of Solids and Structures, 2022. - Fenics_magneto_visco_homogenization.py This python script contains the solver for the magneto-viscoelastic homogenization. Input variables are the tests conditions, such as mechanical and magnetic loads and material properties. Outputs of the solves are some macroscopic results and the .xdmf and .h5 with the full field results. - aux_homog_nl.py This is a python code that contains some functions used by the solver: periodic boundary conditions, input and output preparation. - s30.xdmf and s30.h5 These files are an input geometry example that contains a sphere in the middle of un unitary cube. - Usage instructions Installation of Fenics module is needed. The python modules numpy and matplotlib packages are required. Run Fenics_magneto_visco_homogenization.py to start the simulation.
