Collisions of Deformable Bodies and Phase Change
Let us consider again a piece of ice colliding with a warm soil. Work is mostly dissipated on the contact surface and in its neighbourhood. Thus the temperature discontinuity is more important in this zone and some melting may occur there and not elsewhere. In this chapter, collisions of deformable solids with volume dis- continuities of velocity are investigated together with the resulting phase changes. We introduce percussions related to volume velocity discontinuities and to phase volume fraction discontinuities. We assume the contact surface of the colliding solids is conformal, i.e., it has a nonzero Lebesgue measure.
