Notched graphite polymimide composites at room and notched graphite polymide composites at room and elevated temperatures [PDF]

The fracture behavior in graphite/polyimide (Gr/PI) Celion 6000/PMR-15 composites was characterized. Emphasis was placed on the correlation between the observed failure modes and the deformation characteristics of center-notched Gr/Pl laminates.

Simulation of microscopic fracture characteristics of fractured rock based on CZM-FDEM method

Scientific Reports
Microstructural damage is an important cause of macrofracture in fissured rocks. To investigate the microscopic fracture mechanism of fissured rocks, a fissured rock model was established using the CZM-FDEM method.

Some Micromechanical Aspects of Damage and Fracture

Acta Polytechnica, 2000
The failure mode is described by means of elasto-plastic fracture mechanics and the main aspects of fatigue crack behaviour are itemized. The crux of the matter is the presentation of the pplicability limits of the three substantially different fatigue ...

A permeability evolution model of high-pressure waterflooding with dual-fractal characteristics of mechanical properties and fracture structures

Frontiers in Earth Science
The complexities of evaluating permeability evolution during high-pressure waterflooding and subsequent production are primarily governed by rock mechanical damage and extensive microfracture deformation.

Analysis of the Damage Evolution in Steel Specimens under Tension by Means of XRCT [PDF]

, 2017
When a steel specimen is tested under tension, damage usually develops evenly all along the specimen, finally necking and leading to the typical cup-cone fracture surface.
