Rock bolts are widely used in tunnels, underground openings, and also rock slopes to provide support and attach blocks to the
rock mass in various engineering fields. They have a significant role for the stability of underground structures and natural rock slopes both
in the mining and civil engineering industry. The understanding of the rock bolt behavior under stress conditions plays a key role in the long
term stability and sustainability of rock slopes, nearby structures, and underground openings. The detection of the failure type and the
investigation of failure behavior can be supported by thermal imaging of certain regions on the anchor bolt during tensile testing. In this
context, anchor bolt behavior under tensile testing with a force controlled testing environment was analyzed with a LWIR (Longwave
Infrared) thermal camera. The heat dissipation during experiments was recorded by a thermal camera together with the force reading from
the hydraulic press data logger. As a result of the experiments, it was seen that there is a relation between the temperature change and bolt
failure behavior. Therefore, it is expected that this study will provide an opportunity to detect the failure characteristics of the anchor bolts
under tensile strength test by the help of infrared thermal camera.
