Deformation behavior of super-austenitic stainless steel sandwich panels subjected to air blast and underwater explosion
Super-austenitic stainless steels (SASS), characterized by their high Cr–Ni–Mo alloying content, have attracted increasing attention for structural applications that demand exceptional corrosion resistance, high ductility, and robust energy-absorption capacity. When these advanced alloys are incorporated into sandwich panel configurations—typically consisting of two face sheets and a lightweight core—they offer a promising solution for protective structures […]
