Gouging is a phenomenon of large non-linear deformations which may lead a permanent damage on a rocket-sled system. To analyze how gouging occurs and tracing of its development with different matching and rail irregularities, the influences of material matching and rail irregularities on hypervelocity gouging are studied by MPM algorithm in this paper. 5 sets of material matching and 5 set of rail irregularities cases have been simulated in this paper. The results show that gouges would be easier to occur with a lower yield strength material or a rail with irregularities. These results can help us find the methods to avoid gouging.
