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
