Phase Separation Coupled with Damage Processes

Abstract

The existence results for weak solutions from Chapter 4 are generalized to a broader class of coupled PDE systems in this chapter. More specifically, we will be able to treat

  • multi-component Cahn-Hilliard systems,

  • inhomogeneous elastic energy densities,

  • chemical potentials of polynomial or logarithmic type,

  • quadratic gradient term of the damage variable in the energy, i.e., p= 2 in (1.3).

Additionally, we show that the results also apply to elastic Allen-Cahn systems coupled with damage processes. This case is even easier to treat.
