Abstract: For oil and gas exploitation engineering, it is significant to study the interaction between hydraulic fracture (HF) and natural fracture (NF). An extended peridynamic (PD) model for hydraulic fracture analysis is presented, ...

Abstract: Finite element limit analysis (FELA) was used to investigate the bearing capacity of strip footing on a rock mass with single or multiple continuous voids. The underlying rock mass was assumed to have perfect plasticity ...

Abstract: Coal is a complex porous medium. When gas exists in the coal body, the fissure structure of coal and the occurrence of gas adsorption make the stress state of gas-bearing coal different from that of ordinary coal. Therefore, ...

Abstract: Mining disasters such as coal and gas outbursts and rock bursts seriously threaten safe coal mining. Accordingly, it is important to analyze the dynamic damage characteristics of gas-bearing coal and achieve safe coal ...

Abstract: Two plasma spray techniques have been developed to produce membrane-type solid oxide fuel cell (SOFC) units with the advantages of consecutive integrated cell fabrication, high efficiency, good ...

Abstract: Photovoltaic/thermal (PV/T) collector is a novel collector which incorporates photovoltaic power generation and low-temperature heat utilization of solar energy. In this paper, a three-dimensional (3D) physical model of ...

Abstract: Sediment oxygen demand (SOD) can be a significant oxygen sink in various types of water bodies, particularly slow-moving waters with substantial organic sediment accumulation. In most settings in which SOD is a concern, ...
