When the piece was in use under a burden that has changed the size and direction of the ring or liability. (Cyclic loading), the force caused by the vibration result in stress ring (cyclic stress) in engineering leading to parts of the ongoing changes of the material and level of concurrency flaws fixed commas. Increase the burden caused by periods of expansion until the cracks of cracks and damage.The relationship between the size of damages Mechanism of the ring from the burden of any accumulated Stress value graph below y, which causes cause cumulative damage. From the image shows the changes that occurred. To stop the machine to measure the Crack initiation replica. Some of the pieces work as a plastic deformation, with changes from the accumulated from that load from the controller causes of death to find a piece of work.To resolve this problem is to change the value from the controller to reduce the load from the pull force to 0 to help anchor the age of.
