Main purpose

This instrument is used to test the flexural damage resistance of samples after reciprocating bending; Wrap a rectangular sample strip around two opposing cylindrical positions to make the sample cylindrical. One of the cylinders moves back and forth along its axis, causing the sample cylinder to alternately compress and relax, resulting in folding on the sample. This folding continues until a predetermined number of cycles or significant damage occurs to the sample.
