function of principal stretches; equilibrium equations; stored-energy function
Summary: The conditions for the strong ellipticity of the equilibrium equations of compressible, isotropic, nonlinearly elastic solids are expressed in terms of the stored-energy function regarded as a function of the principal stretches. The applicability of this reformulation is illustrated with two specific examples.
