ASTM D6115 Fatigue Delamination Growth of Fiber-Reinforced Polymer Matrix Composites

0 0

ASTM D6115 determines the number of cycles (N) for the onset of delamination growth based on the opening mode I cyclic strain energy release rate (G), using a Double Cantilever Beam (DCB) specimen. ASTM D6115 applies to constant amplitude, tension-tension fatigue loading of continuous fiber-reinforced composite materials.
