1. Introduction 1. Introduction

Heterogeneous materials, in the context of materials science and engineering, refer to materials that exhibit varia tions in their composition, structure, or properties over di ff erent length scales. These variations can occur at di ff erent scales and can manifest as di ff erent phases, grains, inclusions, porosity, or other structural features within the material that lead to orientation-dependent properties (Torquato and Haslach Jr, 2002; Cowin, 2013).
