These experiments quantify the evolution of all contact forces inside soft particle packings exposed to compression, shear and the intrusion of a large intruder. The experimental set-ups and processes are presented and the data are concomitantly published in a repository %G English %2 https://hal.science/hal-02426418/document %2 https://hal.science/hal-02426418/file/Art_Bares_al_Granular_Matter_2020.pdf %L hal-02426418 %U https://hal.science/hal-02426418 %~ UNIV-RENNES1 %~ INRIA %~ INSA-RENNES %~ INRIA-BORDEAUX %~ INRIA_TEST %~ LGCGM %~ TESTALAIN1 %~ TESTBORDEAUX %~ INRIA2 %~ UR1-HAL %~ UR1-SDLM %~ TEST-UR-CSS %~ UNIV-RENNES %~ INSA-GROUPE %~ UR1-MMS %~ INRIAARTDOI %~ INRIA-ETATSUNIS
