Cj. Zhu, CONVERGENCE OF THE VISCOSITY SOLUTIONS FOR THE SYSTEM OF NONLINEAR ELASTICITY, Journal of mathematical analysis and applications, 209(2), 1997, pp. 585-604
In this paper some special entropy pairs of Lax type are constructed f
or the system of nonlinear elasticity, in which the progressive terms
are functions of a single variable. The necessity estimates for the ma
jor terms are obtained by using the theory of singular perturbation of
the, ordinary differential equations. The special entropy pairs are u
sed to prove that the family of Young measures uniquely determined by
the viscosity solution sequence is a family of Dirac measures. Hence,
a convergence theorem on the viscosity solutions is established by app
lying the method of compensated compactness. (C) 1997 Academic Press.
