Japan atomic energy research institute (JAERI) is promoting to construct the liquid metal target as a neutron source of neutron scattering experiment facility. The liquid metal target is planned to receive MW class proton pulse beam and high-intensity spalletion reactions occur in the target generating neutorons. Under such condition, high density heat is released and consequently strong pressure wave is generated. The pressure wave propagates through mercury and reflects on the container of target made of hard stainless steel. On the other hand, in some experiments, the fact is shown that some pits type scratch is created on wall when strong pressure wave reflects on it. If the phenomenon happens in mercury target, it makes the life span of container shorter. Therefore, a coupled simulation study was carried out to reveal the process of the scratch generation.
