Abstract

In this paper，we study the elastic potential energy of an elastic sphere when it is deformed into a

long rotating ellipsoid while keeping its volume constant. Firstly，the displacement function is determined by the

principle of minimum potential energy and physical conditions. Then，according to the relationship among elastic

potential energy density，strain and displacement，the elastic potential energy is obtained by integral calculation，

and the beneficial discussion is made.

Key words： elastic ball; elastic potential energy; principle of minimum potential energy; strain tensor; displacement function
