Sažetak
X-Ray Computed Tomography (XCT) has given a great impetus to material sciences as it provides 3D images of scanned microstructures. Coupling XCT with Digital Volume Correlation (DVC) enables for in-situ measurements of bulk displacements and calculations of strain maps in the 3D space. However, the major limitation of XCT imaging is the acquisition time, which governs the number of possible acquired scans during each test. Due to the low temporal resolution, the material behavior between two consecutive scans is not accessible. This limit does not allow for the identification of e.g. time-dependent behavior. The recently developed projection-based Digital Volume Correlation (P-DVC) aims to surpass low temporal resolutions of scan-wise DVC approaches. Huge gains in terms of acquisition time and testing duration can be reached, as well as the complete loading history that can be analyzed. The aim of the present work is the 4D (i.e., 3D space and time) characterization of an in-situ cyclic tensile test performed on a dogbone specimen containing a single rectangular notch. 3D displacement fields are measured considering a series of 2D radiographs acquired at different angles during the prescribed loading history. The results obtained employing the P-DVC route are compared with DVC measurements at the same loading level.
