We describe here experiments on the mechanics of hydrogel particle packings from the Behringer's lab, performed between 2012 and 2015. 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
