Impact experiments of porous gypsum-glass bead mixtures simulating parent bodies of ordinary chondrites: Implications for re-accumulation processes related to rubble-pile formation

► We studied collisional processes of ordinary chondrite parent bodies. ► We used a gypsum target including mm to sub-mm glass beads simulating chondrules. ► We found that the glass beads caused the decrease of impact strength drastically. ► Their fragment velocities in catastrophic disruption were smaller than other rocky bodies. ► We concluded that chondrules in parent bodies enhanced rubble-pile formation.
