The influence of a weakening interphase region on the macroscopic strength of metal-matrix composites (MMCs) is investigated. Assuming the three phases of the composite to be elastic-perfectly plastic, theoretical bounds to its macroscopic strength domain are derived by applying the fundamental theorems of limit analysis within the framework of homogenization theory for periodic media. Analytical expressions are obtained for the bounds to the macroscopic strength under special uni- and two-dimensional stress conditions.

Abstract
The influence of a weakening interphase region on the macroscopic strength of metal-matrix composites (MMCs) is investigated. Assuming the three phases of the composite to be elastic-perfectly plastic, theoretical bounds to its macroscopic strength domain are derived by applying the fundamental theorems of limit analysis within the framework of homogenization theory for periodic media. Analytical expressions are obtained for the bounds to the macroscopic strength under special uni- and two-dimensional stress conditions.File in questo prodotto:
