The addition of copper nanoparticles reduces the surface un-evenness of steel, which then limits the number of stress risers and hence fatigue cracking. Advancements in this technology through the use of nanoparticles would lead to increased safety, less need for regular inspection, and more efficient materials free from fatigue issues for construction.
Adding copper nanoparticles to steel lowers its surface unevenness, reducing the number of stress points that can lead to fatigue cracks. This advancement in nanotechnology promises safer structures with less need for frequent inspections and more durable materials resistant to fatigue damage.
