Introduction

All solid materials can deform, stretch, compress, bend, flex, shear, twist, or otherwise deviate from their original unstressed sizes and shapes when subjected to external forces or internal thermal stresses. This propensity of materials to deform under exerted forces is a critically important consideration in the design of any mechanical component whose operation depends on its ability to sustain loads or to maintain dimensions within specified tolerances. Especially important is the condition known as elastic deformation.

The deformation produced by an external force acting on a solid is said to be elastic when removing the external force returns the solid to its original undeformed state.

The present compilation of elastic moduli data for polycrystalline oxide ceramics includes Young's modulus, shear modulus, bulk modulus, and Poisson's ratio. The data have been collected from the technical literature, either as reported in textual or tabular formats or as digitized from graphical formats. Special attention has been given to the dependence of the moduli on porosity and temperature.
