Structural stabilities of simple crystals (h.c.p., f.c.c., and b.c.c.) are investigated using both, two‐body and three‐body interactions. A parametrical analysis is performed. The results emphasized the importance of multibody forces to explain structures such as b.c.c. Furthermore, calculations predict that, in general, the stability of crystals changes as h.c.p. → f.c.c. → b.c.c. with increasing intensity of three‐body interactions. For selected cases the possibility of structural transformations (such as b.c.c. → f.c.c.) are discussed.
