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 کاملThe Effect of Hydrogen Content and Welding Conditions on the Hydrogen Induced Cracking of the API X70 Steel Weld
In this study, first,diffusible hydrogen of cellulosic electrode E8010-P1 and low hydrogen electrode E8018-G was measured by mercury displacement method according to ISO3690. Then,the effect of preheating and post-heating on the sensitivity to hydrogen inducedcold cracking in welding of 18mm API5L X70 steel with these electrodes was investigated according to ISO17642-2. The results of visual in...
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 کاملIntelligent Methodology for Sensing, Modelin and Control of Pulsed GTAW: Part l Bead-on-Plate Welding
This study addresses intelligent techniques for fulfilling quality control of bead-on-plate welding. A new visual double-sided sensing system capable of imaging the weld pool topside and backside simultaneously in a frame was provided to determine the weld pool geometry parameters. The imaging principle was analyzed with spectrum distribution, in which the weld pool was illuminated by arc light...
