Internal stress anisotropies induced by electric field in lanthanum modified PbTiO3 ceramics
TL;DR: In this paper, the anisotropy of internal stress generated by applying a poling field was measured using a microindentation technique using Lanthanum modified lead titanate, (Pb0·775La0·15)TiO3 ceramics.

Toughening and strengthening mechanisms of porous akermanite scaffolds reinforced with nano-titania
TL;DR: In this paper, nano-titania (nano-TiO2) was dispersed into the ceramic-matrix to enhance the mechanical properties of porous akermanite scaffolds fabricated with selective laser sintering (SLS).

The effect of elevated-temperature neutron irradiation on fracture toughness of ceramics
TL;DR: In this paper, single-crystal forms of MgAl/sub 2/O/sub 4, Y/sub 3/al/sub 5/O 12/12/12/, and Al/sub 1/O 3/O 4/O 6/O 7/O 8/O 9/O 10/O 11/O 13/O 14/O 15/O 16/O 17/O 18/O 19/O 20/O 21/O 22/

Trapped cracks at indentations
TL;DR: In this article, a series of yttria-tetragonal zirconia polycrystals (Y-TZP) with a range of grain sizes were examined and two distinct types of cracks were found to exist.

On the fracture toughness of bulk metallic glasses under Berkovich nanoindentation
TL;DR: In this article, the authors proposed an indentation protocol to evaluate indentation fracture toughness based on two key considerations: first, the plastic deformation induced damage to the characteristic fracture initiation point calculated from integrating the indentation load-displacement curves is obtained and used to estimate indepth fracture toughness.

Electron microscopy of microcracking about indentations in aluminium oxide and silicon carbide
Bernard J. Hockey,Brian R. Lawn +1 more
TL;DR: In this article, the authors examined the nature of microcracking about small-scale indentations in two highly brittle solids, sapphire and carborundum, and found that cleavage steps comprise the main source of obstruction to lattice restoration across the interfaces.

- 14 Feb 1976
TL;DR: In this article, a three part study of indentation fracture in the plastic contact regime is presented, where the first part summarizes the observations of fracture and develops a fracture classification scheme, the second part discusses the implications of the fracture characterization for fracture toughness determinations, and abrasive wear and low velocity erosion prediction.

A simple method for studying slow crack growth.
D. P. Williams,A. G. Evans +1 more
TL;DR: In this article, a simple method for studying slow crack growth is described, which entails measurements of load relaxation at constant displacement using a double torsion specimen, and it is demonstrated that the data generated using this technique are in excellent agreement with data obtained using the more complex conventional techniques, for a range of materials - steel, titanium, glass, aluminum oxide, PMMA.
