An automatic loading system for rock core testing with an industrial CT scanner

摘要

A new type of a loading and measuring system was developed for testing failure and deformation of rock core samples with an industrial CT (ICT) scanner.The loading and measuring system consisted of a loading system and a computer control system.The maximum servo-controlled force was 2 tonnes.The new system was a high-stiffness system with a small size.During ICT tests,rock core samples could be easily loaded in the axial direction.So the initiation,propagation,and coalescence of cracks in core samples were observed on ICT images.
