Functionally graded materials (FGMs) are innovative materials whose composition and/or
microstructure gradually vary in space according to a designed law. As a result, also the …

The mechanical response of materials with spatial gradients in composition and structure is
of considerable interest in disciplines as diverse as tribology, geology, optoelectronics …

In this article we review the nature and mechanics of damage induced in ceramics by
spherical indenters, from the classical studies of Hertz over a century ago to the present day …

Systematic studies have been performed to investigate the composition effects of ZrO2-
based thermal barrier coating (TBC) ceramics on their interactions with molten Ca–Mg–Al …

Indentation is a remarkably flexible mechanical test due to its relative experimental
simplicity. Coupled with advances in instrument development, ease of implementation has …

Airborne sand particles that deposit on thermal barrier coatings (TBCs) in gas-turbine
engines melt and form calcium–magnesium–aluminosilicate (CMAS) glass, which attacks …

There has been growing interest in incorporating single-wall carbon nanotubes (SWNTs) as
toughening agents in brittle ceramics. Here we have prepared dense Al2O3/SWNT …

The high-temperature (1500° C) interactions of two promising dense, polycrystalline EBC
ceramics, β-Yb 2 Si 2 O 7 and β-Sc 2 Si 2 O 7, with a calcia-magnesia-aluminosilicate …

The London dispersion forces, along with the Debye and Keesom forces, constitute the long‐
range van der Waals forces. London's and Hamaker's work on the point‐to‐point dispersion …

Yttria stabilized zirconia (YSZ) thermal barrier coatings (TBCs) are used to protect hot-
components in aero-engines from hot gases. In this paper, the microstructure and thermo …
