Material properties of 2024-T3 ALCLAD and 2124-T851 aluminum alloys using 2D and 3D Digital Image Correlation techniques

摘要

To characterize the rate dependency of materials using various testing machines, specimen geometries of materials are oftentimes required to be modified in order to fit on particular testing machine. Using well stablished standards for static tests may not be a practical choice for high strain rate testing machines such as Split Hopkinson Bar. The scope of this work is to propose and validate modified specimen geometries that could substitute standard geometries. Therefore, series of experiments were carried out on 2024-T3 ALCLAD and 2124-T851 aluminum alloys using Digital Image Correlation technique as a measurement method.
