The group is conducting research to detect cracks by infrared imaging. The thermal energy change is measured after photographing the frictional heat caused by the crack with a thermal infrared camera. The group has applied thermal infrared images to measure the failure behaviour of pillars in tunnels and crack patterns in frozen soil.
