Hardness and fracture toughness of brittle materials:

2004-11-18  Abstract. The focus of the paper is to study the correlation between hardness and fracture toughness of brittle materials. To this end, density functional theory (DFT) is used to calculate materials parameters such as the surface energies, the unstable stacking fault energies, the Young’s modulus, the bulk modulus, the shear moduli, and the

Study of hardness and deformation of brittle materials

2019-3-18  We investigated controlling parameters of hardness in brittle materials by exploring the correlation between hardness and shear mode cracking. Density functional theory was used to calculate the unstable stacking energies (shear resistance to irreversible deformation) and the surface energies (tension resistance to fracture) for comparison. We found that both the unstable stacking energies and

Hardness and fracture toughness of brittle materials:

2004-11-1  We find that the theoretical fracture toughness, proportional to the product of shear modulus and surface energy, can better characterize hardness of diamond, cBN,B 6 O,3C SiC,Si, and possibly other brittle materials than shear modulus alone [D. M. Teter, MRS Bull. 23, 22 (1998)]. This finding could be helpful in searching for new hard materials.

Effect of erodent hardness on erosion of brittle

1988-12-1  The damage pattern produced by the impact of hard, irregularly shaped particles on brittle materials have in general produced crack patterns that resemble those produced during quasi-static indentation using sharp diamond indenters.

What is Hardness of Materials? Definition from

2013-12-3  Scratch hardness tests are usually performed on brittle materials, such as ceramics and minerals because they do not undergo plastic deformation. This type of hardness is quantified on a scale known as the Mohs Scale, which is based on the relative scratch hardness of various materials.

Indentation of Brittle Materials ASTM International

The use of indentation testing as a method for investigating the deformation and fracture properties of intrinsically brittle materials, glasses, and ceramics is examined. It is argued that the traditional plasticity models of hardness phenomena can be deficient in some important respects, notably in the underlying assumptions of homogeneity and volume conservation.

Hardness UMD

2007-9-7  This test method was devised in 1939 by F. Knoop and colleagues at the National Bureau of Standards in the United States. By using lower indentation pressures than the Vickers hardness test, which had been designed for measuring metals, the Knoop test allowed the hardness testing of brittle materials
