Using different parameters on force model

Hi,
i am trying to make a molecular dymamics simulation of granular matter using lamps but i have to type of particles and each one of them has different young modulus and Poisson ration, how can i make lammps to use diferentc parameter for this interacions
particle_type_1 <=> particle_type_1
particle_type_1 <=> particle_type_2
particle_type_2 <=> particle_type_2

Thanks, Miguel

for more complex DEM models, please check out the LIGGGHTS package,
which is a derivative of LAMMPS with specific focus on supporting
granular media simulations.
