Producing a sufficient volume of multiscale crack networks is key to enhancing recovery of shale gas. The formation of crack network largely depends on initiation and propagation of microcracks. To reveal the influence of different loading methods on the propagation of mineral-scale microcracks, this study used the Voronoi tessellation technique to establish a cohesive zone model of shale mineral distribution and applied six different boundary conditions to represent different loading methods. Crack path characteristics, rupture characteristics, continuous crack propagation and turning, and en

A review of the literature reveals potential advantages that papermakers can achieve by placing minerals in the lumens or cell walls of fibers before the pulp is formed into paper. Loading of filler into the fiber lumen by mechanical deposition or within the cell wall by in-situ precipitation has been reported to generally result in a moderate reduction in light scattering coefficient and increased strength properties of laboratory handsheets, as well as in paper manufactured with pilot plant equipment, when compared to conventional addition of filler. However, there are some exceptions to thi

AbstractCorrelations between organic carbon (OC) and fine mineral particles corroborate the important role of the abundance of soil minerals with reactive surfaces to bind and increase the persistence of organic matter (OM). The storage of OM broadly consists of particulate and mineral-associated forms. Correlative studies on the impact of fine mineral soil particles on OM storage mostly combined data from differing sites potentially confounded by other environmental factors. Here, we analyzed OM storage in a soil clay content gradient of 5–37% with similar farm management and mineral composit

Increased mechanical loading of bone with the rat tibia four-point bending device stimulates bone formation on periosteal and endocortical surfaces. With long-term loading cell activity diminishes, and it has been reported that early gains in bone size may reverse. This study examined the time course for bone cellular and structural response after 6, 12, and 18 wk of loading at 1,200–1,700 microstrain (με).

Mineral dust aerosols are composed of a complex mixture of silicates, carbonates, oxides, and sulfates. The minerals’ chemical composition and size distribution are vital parameters to evaluate dust environmental impacts. However, the quantification of minerals remains a challenge due to the sparse in situ measurements of dust samples. Here we derive the size-resolved mineralogical composition of airborne dust aerosols from MODIS (Terra and Aqua) satellite-acquired optical measurements and compare it with chemically analyzed elemental (Al, Fe, Ca, Mg) concentrations of aerosols for PM2.5 and P

Captive insectivores may consume invertebrates as all, or part of their overall diet. The challenge with feeding captive insectivores involves the limited number of invertebrate species that are commercially available, and the lack of key nutrients provided by these insects. Among these insects, a naturally occurring low concentration of calcium and an inverse calcium to phosphorus ratio may put insectivores at the risk of developing hypocalcemia.

AbstractThere are many empirical models for the development of creep and fatigue damage. The perhaps most well-known ones are Robison’s and Miner’s damage summation rules. They are based on the mechanical behavior during monotonous and cyclic loading. To improve the accuracy of the damage assessment, it is important to analyze the changes in the microstructure as well, not least the cavitation. To describe cyclic loading, special empirical models have often been used in the past, some with numerous adjustable parameters. Recently, a model for cyclic loading has been formulated that is based on

A mechanical testing device was developed for testing the behavior of mineral-bonded composites under impact shear loading. The device is based on the well-known double shear specimen configuration and was designed to be used in a gravity split-Hopkinson tension bar (SHTB), enabling shear testing at high loading rates. In this work, results from impact shear testing performed on a normal cementitious matrix (NSM) and strain-hardening cement-based composites (SHCC) tested by means of the new device are presented and discussed. Failure behavior and fracture modes are analyzed using optical measu

The post-yield properties of bone mainly provide the estimation of its toughness and are directly related to the composition and structure of the tissue at basic building unit. Combining the recently developed synchrotron X-ray scattering techniques with a novel progressive loading scheme [1], a recent study has evinced that the internal strain of mineral and collagen phases in bone varies significantly before and after yielding of the tissue [2]. The minerals as well as collagen fibrils in bone have random and preferred orientation distribution according to the location within a body. Such or

A new processing route for making thermosetting materials and products containing high loading solid fillers including waste solid scraps and natural mineral fillers was investigated. Traditionally, solid fillers are incorporated into thermosetting polymers by liquid-state mixing. However, due to the high viscosity in mixing, high loading above 50% by weight is difficult to achieve. The new process overcomes this hurdle by a two-step processing strategy. First, solid fillers are placed in the mold and compacted to conform to the mold shape. Next, with the mold closed, a thermosetting resin is

Overpressure existence represents a geological hazard; therefore, an accurate pore pressure prediction is critical for well planning and drilling procedures, etc. Overpressure is a geological phenomenon usually generated by two mechanisms, loading (disequilibrium compaction) and unloading mechanisms (diagenesis and hydrocarbon generation) and they are all geological processes. This research was conducted based on analytical and descriptive methods integrated with well data including wireline log, laboratory test and well test data. This research was conducted based on quantitative estimate of

Magnetic responsive materials can be used in a variety of applications. For structural applications, the ability to create tunable moduli from relatively soft materials with applied electromagnetic stimuli can be advantageous for light-weight protection. This study investigated magnetorheological composite materials involving carbonyl iron particles (CIP) embedded into two different systems. The first material system was a model cementitious system of CIP and kaolinite clay dispersed in mineral oil. The magnetorheological behaviors were investigated by using parallel plates with an attached ma

Fatigue analysis of welded components and structures according to established codes is based upon either S-N design curves or fracture mechanics principles. Fatigue damage in nominally sound joints is commonly estimated using an appropriate S-N curve in conjunction with a linear cumulative damage rule (i.e., Miner"s rule). By comparison, fracture mechanics is used to assess the growth of an imperfection during a period of cyclic loading, or to assess whether an imperfection will remain dormant under the applied cyclic loading condition. Thus, the S-N approach is used mostly during initial desi
