The term textitsoft emphasizes that no boundaries between particles are defined and every particle possesses a support consisting of a set of adjacent particles. The polynomial interpolation/approximation method is utilized for the evaluation of spatial derivatives using the information carried by particles in supports. The system of equations consisting of spatial derivatives is solved using an iterative nonlinear solver and the computation of the Jacobian matrix is parallelized. The simulations of laboratory tests have been carried out to show the applications and limitations of the current version of SPARC. In addition to the simulations, laboratory (zig-zag) model tests using fine sand were carried out, in which the cyclic tilt of a retaining wall induces a peculiar motion in the backfill (sand), with closed trajectories (eddies). 410 0$aAdvances in geotechnical engineering and tunneling ;$v21. 606 $aGeotechnical engineering 606 $aGranular materials 615 0$aGeotechnical engineering. 615 0$aGranular materials. 676 $a624.151 700 $aChen$b Jianxun$0623461 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910824748503321 996 $aDevelopment of soft particle code (SPARC)$93996623 997 $aUNINA
