3 terms and definitions
The following terms and definitions apply to this document.
3.1
Seam fatigue seamfatigue
Material seams at withstand the periodic load after stretching, caused by the local structural changes and the development of internal defects.
3.2
Pinhole elongation value needleholehole
After the joint fatigue test, the distance between the pinholes on both sides of the specimen.
4 principle
Under the specified test conditions, the sample is periodically fixed load tensile and recovery, the provisions of the number of cycles, the determination of the maximum seams
Pinhole elongation to evaluate the fatigue resistance of the seam.
