A theoretical investigation is undertaken into the creep
instability of two common shells of revolution, the infinitely
long cylinder and the complete sphere. The linear and non-linear
visco-elastic material idealizations are used in the
various theoretical procedures. The critical buckling time
is greatly influenced by the parameter a/h ratio, magnitude
of initial imperfections and material selection. The spherical
shell has a lifetime longer than the cylindrical shell having
the same a/h ratio, initial imperfections and material constants,
while the critical mode numbers are the same.
