Peridynamic simulation of rock fracturing under effect of methane deflagration loading

Meitan xuebao
The methane deflagration fracturing technology impacts and fractures the reservoirs and generates the complicated fracture network by the high-pressure and high-temperature gas, which is generated from the deflagrations of methane desorbed from in-situ ...
