New artificial neural networks for true triaxial stress state analysis and demonstration of intermediate principal stress effects on intact rock strength
Simulations are conducted using five new artificial neural networks developed herein to demonstrate and investigate the behavior of rock material under polyaxial loading. The effects of the intermediate principal stress on the intact rock strength are investigated and compared with laboratory result...
