概要 We consider a model for grain boundary motion with constraint.
In composite material science it is very important to investigate the grain
boundary formation and its dynamics. In this paper we study a phase- led
model of grain boundaries, which is a modi ed version of the one proposed by
R. Kobayashi, J.A. Warren and W.C. Carter. The model is described as
a system of a nonlinear parabolic partial di erential equation and a nonlinear
parabolic variational inequality. The main objective of this paper is to show
the global existence of a solution for our model, employing some subdi erential
techniques in the convex analysis.
