Preloaded Interlocking Metasurfaces
We conceptualize and design a preloaded interlocking metasurface (PIM). PIMs are designed to store an internal preload during assembly to increase the tensile strength of the join in operation. PIMs can also be tailored to contain a specific stress distribution and apply a prestress to sheet metal parts prior to welding to counteract the post-welding...
