Few researchers have looked at the mechanical characteristics of rocks that are composed numerous layers various kinds rock. Most strata in practical engineering composite strata, and fracture propagation is frequently to blame for mishaps. The digital image correlation method (DIC) acoustic emission (AE) equipment were used observe crack strike strain field changes specimens resemble with a co...

The study of strain effects in thermally-forced rock masses has gathered growing interest from engineering geology researchers the last decade. In this framework, digital photogrammetry and infrared thermography have become two most exploited remote surveying techniques applications because they can provide useful information concerning geomechanical thermal conditions these complex natural sys...
