Abstract
The growth and remodeling of soft tissues depend on a number of biological, chemical
and mechanical factors, including the state of tension. In many cases the stress field plays
such a relevant role that "stress­modulated growth" has become a very topical subject.
Recent theoretical achievements suggest that, irrespective of the specific biological mate-
rial at hand, a component of the stress-growth coupling is tissue­independent and reads
as an Eshelby­like tensor. In this paper we investigate the mathematical properties and
the qualitative behavior predicted by equations that specialize that model under few sim-
ple assumptions. Constitutive equations that satisfy a suitable dissipation principle are
