Brittleness revisited
The concept of brittleness plays a crucial role in the development of tight oil and gas as it reflects a rock’s ability to fail and maintain a fracture in a hydraulic fracture experiment. Conventional methods that attempt to quantify the degree of brittleness associated with a rock mass have a few shortcomings. For example, failure criteria are not used and only the effective moduli are conside...
متن کاملOn the Brittleness of Bayesian Inference
With the advent of high-performance computing, Bayesian methods are becoming increasingly popular tools for the quantification of uncertainty throughout science and industry. Since these methods can impact the making of sometimes critical decisions in increasingly complicated contexts, the sensitivity of their posterior conclusions with respect to the underlying models and prior beliefs is a pr...
متن کاملAn Observation of Oxygen Precipitation Retardation Phenomenon Induced by 450°c Anneal in Czochralski Silicon
Two-step (450°C-1000°C) and three-step (1150°C-450°C-1000°C) annealing experiments were carried out to study oxygen precipitation behavior in Czochralski silicon. A distinct retardation of precipitation was observed during the two-step anneal, while the retardation during the three-step anneal was less pronounced. With the three-step anneal, the first high temperature 1150°C anneal in N 2 ambie...
متن کاملTwo-side surface photovoltage studies for implanted iron diffusion in silicon during rapid thermal anneal
Two-side surface photovoltage TS-SPV based on measuring SPV from both wafer sides is proposed as the approach for silicon iron contamination monitoring. TS-SPV is applied to follow diffusion of implanted iron in a lightly doped p-type silicon during rapid thermal anneal RTA . Good correlation is found between the iron distribution versus RTA conditions in the range of 375–1100 °C. The impact of...
متن کاملThe Abrasion and Brittleness Coefficients of Tabriz’s Metro Aggregates
Introduction Urban development and rapid extension of cities have been accompanied by a considerable growth in mechanized tunneling. The abrasivity of rock and even soil is a factor with considerable influence on the wear of tools. Soil abrasion and the resulting tool wear has a major impact on machine operation, utilization, and tunneling costs and time. One of the problematic aspects of work...
