Abstract:

We analyze a phase-field approximation of a sharp-interface model for two-phase materials proposed by M. Silhavy $[$41, 42$]$. The distinguishing trait of the model resides in the fact that the interfacial term is Eulerian in nature, for it is defined on the deformed configuration. We discuss a functional frame allowing for existence of phase-field minimizers and $\Gamma$-convergence to the sharp-interface limit. As a by-product, we provide additional detail on the admissible sharp-interface configurations with respect to the analysis in $[$41, 42$]$.
