Interaction between a circular inclusion and an arbitrarily oriented crack
TL;DR: In this paper, the authors considered the plane interaction problem for a circular elastic inclusion embedded in an elastic matrix which contains an arbitrarily oriented crack, using the existing solutions for the edge dislocations as Green's functions.

On the particle-size dependence of fatigue-crack propagation thresholds in SiC-particulate-reinforced aluminum-alloy composites: Role of crack closure and crack trapping
Jian Ku Shang,Robert O. Ritchie +1 more
TL;DR: In this paper, the role of SiC-particle size and volume fraction on the fatigue-crack growth threshold condition was investigated in P/M Al-Zn-Mg-Cu metal-matrix composites reinforced with either 15 or 20 vol.% silicon carbide particulate.

Microstructure-based modeling of crack growth in particle reinforced composites
A. Ayyar,Nikhilesh Chawla +1 more
TL;DR: In this article, the effects of particle morphology and distribution (homogeneous and clustered) on crack growth have been studied using the finite element method, and the degree of particle clustering in aluminum/silicon carbide composites was quantified by the coefficient of variance in the mean near-neighbor particle spacing, and cluster size distributions obtained by an image analysis technique.

Thermal expansion of rocks; some measurements at high pressure
Teng-fong Wong,W. F. Brace +1 more
TL;DR: In this article, the authors measured coefficients of thermal expansion of rocks under sufficient pressure that the strains were reversible; the coefficients obtained fell close to the theoretical bounds for polycrystalline aggregates calculated by Walsh.

Interaction between an edge dislocation and a circular inclusion
John Dundurs,Toshio Mura +1 more
TL;DR: In this article, exact elasticity solutions are used to discuss the interaction between a circular inclusion and an edge dislocation in the matrix, and it is shown that for certain combinations of material constants, the dislocation has a stable equilibrium position near the interface.

Edge dislocation inside a circular inclusion
John Dundurs,G. P. Sendeckyj +1 more
TL;DR: In this paper, the equilibrium positions of an edge dislocation inside a circular inclusion were investigated using elasticity solutions, and the conditions under which the centre of the inclusion is stable equilibrium position were given.
