The need to accurately determine the mechanical properties of thin foil materials has grown in recent years as the emphasis on hypersonic vehicles and access to space has also increased. In order to meet this need, two separate test systems have been developed in-house as part of a comprehensive program to advance state-of-the-art testing capabilities for thin foils. The first test system, developed using a conventional MTS hydraulic load frame outfitted with specialized capabilities, was designed for determining materials properties on a macro-scale, with specimen sizes on the order of 75-150 mm. The second system was designed to evaluate properties on a micro-scale, with corresponding specimen sizes on the order of 3 mm. This paper outlines the developmental process of each system, including unique challenges, preliminary data, and future considerations.
