In this paper, examined is behavior of a partially molten dust particle with shock-wave heating model. For that purpose, analytically solved were hydrodynamical equations for the core-mantle structure particles with linear approximation and obtained were the deformation, internal flow, and pressure distribution of the particle. Also obtained were conditions in which liquid mantle may be stripped off from the solid core. When a dust particle has a dense structure and the dust radius is larger than about 5 mm, the stripping is expected to occur before the entire dust particle melts. When a dust is porous, the critical size becomes about 2 mm. The stripping may determine the maximal size of chondrules.
