Abstract
For f.c.c. and h.c.p. crystals structural phase transitions involving soft acoustic modes are discussed. A simple nearest neighbour force model is used. Two extreme types of transition are distinguished; one of these entails a softening of all modes whereas in the second type there is only appreciable softening of a single mode.Keywords
