, the predicted stress corrosion crack velocity is then vc = 0.8 μm/0.02 s = 4×10-5 m/s This estimation shows that the DHC model may be developed to predict a TGSCC crack velocity sufficiently high... steady state stress corrosion crack propagation of Mg in aqueous solutions, a high dynamic hydrogen concentration would be expected to build up just behind the crack tip. This may be a feature of all......

to the magnitude of front abutment pressure the stress region can be separated into stress-relaxed area, stress- concentrated area and initial stress area. At the -50 m mining level... soil or rock mass is excavated, the balance of initial stress around empty area will be destroyed, and then, the stress redistributed. If the induced stress exceeds the ultimate strength......
Heidelberg 2016 Abstract: In deep underground mining, the surrounding rocks are very soft with high stress. Their deformation and destruction are serious, and frequent failures occur on the bolt support... and stress of surrounding rocks are improved, the bond strength will increase. So, the anchoring force on surrounding rocks can be effectively improved by employing an anchoring agent with high sand content......
