Th. Qin, GLOBAL EXISTENCE OF WEAK SOLUTIONS TO THE BOUNDARY-VALUE PROBLEM FOR A 3-DIMENSIONAL VISCOELASTIC DYNAMIC SYSTEM, Journal of elasticity, 42(2), 1996, pp. 99-114
In this paper, we prove the global existence of weak solutions to the
boundary value problem of three-dimensional dynamical system for visco
elastic materials of single-integral type, without the assumption that
the equilibrium elastic tensor is definitely positive, i.e. phase tra
nsitions are admitted for the problem.
