Deformation and fracture behavior of vinylester/fly ash composites
(John Wiley & Sons Inc, 2012-07-25)
In this work, the deformation and fracture behavior of a commercial vinylester resin reinforced with fly ash was investigated. Tensile, compressive and fracture tests were performed on the matrix and the composites with ...
Seismoacoustic signatures of fracture connectivity
(American Geophysical Union, 2014-03)
Wave-induced fluid flow (WIFF) between fractures and the embedding matrix as well as within connected fractures tends to produce significant seismic attenuation and velocity dispersion. While WIFF between fractures and ...
Fracture connectivity can reduce the velocity anisotropy of seismic waves
(Wiley Blackwell Publishing, Inc, 2017-07)
The degree of connectivity of fracture networks is a key parameter that controls the hydraulic properties of fractured rock formations. The current understanding is that this parameter does not alter the effective elastic ...
In Vitro Study of Fracture Load and Fracture Pattern of Ceramic Crowns: A Finite Element and Fractography Analysis
(Wiley-Blackwell, 2011-08-01)
Purpose: This in vitro study investigated the null hypothesis that metal-free crowns induce fracture loads and mechanical behavior similar to metal ceramic systems and to study the fracture pattern of ceramic crowns under ...

Seismic attenuation and dispersion in poroelastic media with fractures of variable aperture distributions
(Copernicus GmbH, 2019-08-08)
Considering poroelastic media containing periodically distributed parallel fractures, we numerically quantify the effects that fractures with variable aperture distributions have on seismic wave attenuation and velocity ...
Microstructure and Mechanical Properties of Nb-API X70 Low Carbon Steel
(2021-08-01)
The oil and gas production has grown steadily, and the care with its transportation grid needs to be maintained and expanded. The pipeline used in the transport of gas and oil by-product requires materials with high ...
