Investigation of cable bolts for stress corrosion cracking failure

Premature failure of cable bolts due to stress corrosion cracking (SCC) in mining and civil industries is a worldwide problem with limited cost-effective solutions. A load frame capable of applying tensile loads was designed and constructed to simulate and examine SCC of full-size cable bolts (up to 2.4 m in length) under simulated in-situ conditions. The tension loading apparatus was used to conduct periodically increasing strain rate (PISR)...
