Numerical analysis using FE Forge® and Abaqus code show the importance of the rheological softening terms on the metals fibers morphology and position coordinate. Calibration of friction law and sensitivity of softening parameters corresponding to a Hansel-Spittel rheological equation have been studied. © 2016 Author(s). %G English %L hal-01416484 %U https://univ-rennes.hal.science/hal-01416484 %~ UNIV-RENNES1 %~ INSA-RENNES %~ LGCGM-INSA %~ LGCGM %~ STATS-UR1 %~ GENIECIVIL %~ UR1-HAL %~ UR1-SDLM %~ TEST-UNIV-RENNES %~ TEST-UR-CSS %~ UNIV-RENNES %~ INSA-GROUPE %~ UR1-MMS
