Strain amplitude controlled fatigue of Flax-epoxy laminates

Fatigue longevity and evolving material properties of Flax-epoxy laminates is examined under constant strain amplitude cycling. Several recent fatigue studies on Flax-composites, all of which were conducted under stress-control, found that certain laminates demonstrate a modulus increase over fatigue life, even while accumulating internal damage and permanent deformation. This study investigates whether such fatigue-stiffening phenomena are also...
