TLDR
In this paper, it was shown that a crack front increases its length by changing its shape when it interacts with two or more inhomogeneities in a brittle material, and an expression for the fracture energy was obtained.Abstract:
Observations are presented showing that a crack front increases its length by changing its shape when it interacts with two or more inhomogeneities in a brittle material. These observations are presented for both cleavage and conchoidal types of fracture. Based on these observations and the concept that a crack front possesses a line energy, an expression for the fracture energy is obtained. This expression shows that the fracture energy should increase as the distance between the dispersed inhomogeneities is decreased. Using the Griffith fracture criterion, this result is discussed for the case of strengthening a brittle material.read more

TL;DR: In this paper, the mechanical behavior of MoSi2 reinforced-Si3N4 matrix composites was investigated as a function of the phase content, the phase size, and the amount of MgO densification aid for the Si 3N4 phase.

Role of mineral filler in asphalt mixture
TL;DR: In this article, fine-grained mineral particles naturally present in or manufactured and added to aggregates play a significant role on the performance of asphalt mastic and asphalt mixtures.

Reactive Polymers: Fundamentals and Applications
TL;DR: Cyanoacrylates were commercially introduced in 1950 by Tennesee Eastman Company as mentioned in this paper and are monomeric adhesives, which are generally quick-setting materials which cure to clear, hard glassy resins, useful as sealants, coatings, and particularly adhesive for bonding together a variety of substrates.

The Phenomena of Rupture and Flow in Solids
TL;DR: In this article, the authors investigated the effect of surface scratches on the mechanical strength of solids, and some general conclusions were reached which appear to have a direct bearing on the problem of rupture, from an engineering standpoint, and also on the larger question of the nature of intermolecular cohesion.

LXXV. The moving griffith crack
TL;DR: In this article, a straight crack moving through an elastic medium is calculated and the stresses depend on the velocity and reduce to Inglis' solution when the velocity is zero, and the results may be applied to the spicular fracture of glass.

Fracture Surface Energy of Glass
TL;DR: In this article, the double-cantilever cleavage technique was used to measure the fracture surface energy of six glasses and the results ranged from 3.5 to 5.3 J/m2 depending on the chemical composition of the glass and the temperature of the test.
