Impact and indenting damage of CVD-produced ZnS and ZnSe ceramics
Time series of acoustic emission pulses were excited in ductile ZnS and ZnSe ceramics either by a falling weight or by indenting the Vickers pyramid. Energy distributions in emitted acoustical emission pulses were found to be random (Poisson-like) in the

Energy-Efficient Fracturing Based on Stress-Coupled Perforation [PDF]
Hydraulic fracturing is one of the key technologies for reservoir stimulation in low-permeability/unconventional oil and gas fields. In response to the high energy consumption and greenhouse gas emissions caused by extreme flow-limiting perforation in hydraulic fracturing, stress-coupled perforation technology has been proposed to promote low-energy ...

Finite element modelling of thin intermetallic compound layer fractures
A thin intermetallic compound (IMC) of solder ball joint induces strong stress concentration between the pad and solder where a crack propagated near the IMC layer.

Fracture network characterization with deep generative model based stochastic inversion [PDF]
The distribution of fracture network is crucial to characterize the behaviors of flow field and solute transport, especially for enhanced geothermal systems, as fractures provide preferential flow paths. However, estimating the parameters of the fracture networks and quantifying their uncertainties based on observing data is a nontrivial task because ...

In this paper, stress intensity factor (SIF) solutions of eccentric annular external cracks in elliptical notched round bars under tension loading have been obtained from 3D finite element analysis, along with their relation to the energy release rate ...

Multi-scale approach to invasion percolation of rock fracture networks [PDF]
A multi-scale scheme for the invasion percolation of rock fracture networks with heterogeneous fracture aperture fields is proposed. Inside fractures, fluid transport is calculated on the finest scale and found to be localized in channels as a consequence of the aperture field. The channel network is characterized and reduced to a vectorized artificial

This article studies the retardation effect in plasticity-induced fatigue crack growth rate for a low-medium strength steel, due to the appearance of microdeflections in the crack path.

Tensile Fracture Behavior of Progressively-Drawn Pearlitic Steels
In this paper a study is presented of the tensile fracture behavior of progressively-drawn pearlitic steels obtained from five different cold-drawing chains, including each drawing step from the initial hot-rolled bar (not cold-drawn at all) to the final
