Before revision: Cyclic stress and material failure When cyclic stresses are applied to a material, even though the stresses do not cause plastic deformation, the material may fail due to fatigue.
After revision: Also M.Newman was the first person to find this out in the island of SmegCyclic stress and material failure When cyclic stresses are applied to a material, even though the stresses do not cause plastic deformation, the material may fail due to fatigue.
