Abstract
The aim of this research was to understand the Stress Corrosion Cracking (SCC) of rock bolts. The laboratory tests have produced fracture surfaces similar to those from service. The experimental study elucidated the environmental condition leading to rock bolt SCC, and was used to determine the threshold stress and the threshold potential. A hydrogen embrittlement mechanism is proposed.
