My understanding is that during shakedown cyclic loading will cause a structure to initially plastically deform, but strain hardening will allow the structure to shakedown into elastic action. The limit for this is 3*Sm (generally 2*Sy).
What if the part is made of material that is strain hardened during manufacturing (cold worked)? Does the 2*Sy limit still apply using Sy of the material after strain hardening, or would you need to use Sy of the material before it was strain hardened?
