Experimental investigation on mode I fracture characteristics of granite after cyclic heating and cooling treatments

Engineering Fracture Mechanics, 2019
Rock in the geothermal reservoir is frequently subjected to cyclic heating and cooling, and fracture characteristics are closely related to the stable operation of Enhanced Geothermal Systems.

Introduction to Creep Fracture and Other Fracture Modes

1987
The acceleration of creep in the tertiary stage of the creep curve is often caused by the formation and joining of micro-cavities on grain boundaries. Creep fracture is therefore generally intergranular. The cavities may be nucleated early in the creep life, possibly even during the primary stage.

On the Self-Healing Fracture Mode

Bulletin of the Seismological Society of America, 2003
We present the analytical solution for a fundamental fracture mode in the form of a self-similar, self-healing pulse. The existence of such a fracture mode was strongly suggested by recent numerical simulations of seismic ruptures but, to our knowledge, no formal proof of their origin has been proposed yet.

Fracture modes in fiber networks

Physica A: Statistical Mechanics and its Applications, 1995
Abstract Two-dimensional fiber networks of varying disorder are studied with a quasi-one-dimensional model. When disorder increases, the process of fracture in the localized stage evolves continuously from crack propagation to uncorrelated microcracking. In larger systems the transition takes place over a narrower range of disorder.

Fracture toughness analysis of HCCD specimens of Longmaxi shale subjected to mixed mode I-II loading

, 2020
Longmaxi shale exhibits strong anisotropy due to its bedding planes induced by diagenesis. The anisotropic properties of shale have a significant effect on the stability control of geotechnical engineering.

The effect of in-plane layer orientation on mixed-mode I-II fracture behavior of 3D-printed poly-carbonate specimens

, 2020
Mechanical components produced by the 3D-printing technique contain small voids by nature, which make them susceptible to fracture. Therefore, understanding the fracture behavior of these components improves the applicability of this manufacturing method.

Mixed-mode fracture of concrete

International Journal of Fracture, 1988
Mixed-mode fracture of concrete is encountered frequently in design of concrete structures. To accurately analyzed and design a concrete structure, it is essential to understand the failure mechanisms of concrete under mixed-mode types of loading. A model, which was originally proposed for mode I failure of concrete, is extended to characterized mixed ...

Fracture modes in tungsten wire

Journal of the Less Common Metals, 1976
Abstract Room-temperature fracture of extremely fibrous, heavily-worked tungsten wire involves combinations of three fracture modes: cleavage, grain boundary delamination, and necking of individual grains. Cleavage occurs on {110} planes with, or without, concomitant necking. Ductile fracture is preceded by micro-grain boundary delamination resulting
