In the recent years we have performed various experiments on the collision dynamics of highly porous dust aggregates and although we now have a comprehensive picture of th micromechanics of those aggregates, the macroscopic understanding is still lacking. We are therefore developin g a mechanical model to describe dust aggregate collisions w ith macroscopic parameters like tensile strength, compressiv e strength and shear strength. For one well defined dust sampl e material, the tensile and… CONTINUE READING
