The evolution of the force distributions during the isotropic compression oftwo dimensional packings of soft frictional particles is investigatednumerically. Regardless of the applied deformation, the normal contact forcedistribution can be fitted by the product of a power-law, and a stretchedexponential, while the tangential force distribution is fitted well by aGaussian. With increasing strain, the asymptotic behavior at large forces doesnot change, but both normal and tangential distributions exhibit a broadening,even though, when scaled with the average forces, their widths decrease.Furthermore, the distribution of friction mobilization is a decreasing functionof the mobilization, except for an increased probability of fully mobilizedcontacts. The excess coordination number of the packings increases with theapplied strain, indicating that the more a packing is compressed the morestable it becomes.
