A non-local equation of state describes the components of the energy-momentum tensor not only as a function of a point, but as a functional throughout the enclosed configuration. In this work, we show that it is possible to obtain physically acceptable conformally flat, anisotropic matter distributions that satisfy a non-local equation of state. The evolution of such objects is presented, determining for the quasi-static case the conditions for thermic-peeling effect.

Keywords : Non-local equation of state; relativistic anisotropic matter distributions; conformally flat metrics; thermic peeling.
