This equipment has a temperature chamber, in which it applies repeated flexures on 20 test samples and captures images of cracks generated by the mechaninal fatigue and growing on the samples using a CCD camera to evaluate durability of the samples. It stops in every preset interval to capture images and store them on a PC. Crack width can be measured automatically or manually. In manual mode, measurements can be done with a mouse on a captured image. Data can be edited afterwards. It is possible to draw a S-N curve showing crack width over the number of flexures.
