Abstract
Abstract Ultra-thin stainless steel foils have garnered significant attention due to their exceptional mechanical properties, including light weight, high strength, toughness, corrosion resistance, oxidation resistance, high temperature resistance, and superior shielding properties. In this study, we conducted experimental tests to evaluate the mechanical properties of ultra-thin stainless steel foils, focusing on the determination of Young’s modulus and yield stress for two distinct thicknesses of steel foils. Furthermore, employing both experimental and numerical simulation methodologies, we investigated the impact of wrinkles on the fracture toughness of steel foils containing central cracks subjected to tensile loading. The findings presented in this paper not only contribute to a comprehensive understanding of the mechanical behavior of ultra-thin stainless steel foils but also serve as a fundamental basis for subsequent numerical simulations and fracture toughness estimations. This research lays the groundwork for advancing the development and utilization of ultra-thin stainless steel foils across various industrial applications.
