Abstract

The increasing use of functionally graded materials (FGMs) has propounded their careful consideration for high performance engineering applications. This interest has been largely nurturing challenging applications and prospects in various scientific and technological fields due to the increasing number of available fabrication processes. Among all, field assisted sintering technology (FAST), also known as spark plasma sintering (SPS), has been demonstrated as an efficient method for their throughput fabrication. In this regard, understanding the properties of these advanced sintered materials is critical to serve as the baseline for their development and optimization. Recently, a few peculiar experimental correlations of FGMs to their monolithic equivalents, when exclusively obtained by FAST/SPS, have been documented in the literature. In particular, a moderate anisotropic behavior of sintered samples is observed, though the existing gradient structure due to the spatial variation of volume fraction of reinforcing particles. This paper primarily aims to establish a theoretical criterion by taking advantage of the claimed moderate anisotropy of FGMs and provide a quantitative assessment tool for their effective elastic properties. Repercussions are stated, theoretically formulated, discussed and validated with reference to a set of experimental measures.

期刊介绍： Mechanics Research Communications publishes, as rapidly as possible, peer-reviewed manuscripts of high standards but restricted length. It aims to provide: • a fast means of communication • an exchange of ideas among workers in mechanics • an effective method of bringing new results quickly to the public • an informal vehicle for the discussion • of ideas that may still be in the formative stages The field of Mechanics will be understood to encompass the behavior of continua, fluids, solids, particles and their mixtures. Submissions must contain a strong, novel contribution to the field of mechanics, and ideally should be focused on current issues in the field involving theoretical, experimental and/or applied research, preferably within the broad expertise encompassed by the Board of Associate Editors. Deviations from these areas should be discussed in advance with the Editor-in-Chief.
