| Abstract Scope |
There has been an extensive amount of research in small-scale mechanical testing (SSMT) because of its significant potential in extracting mechanical properties using small-scale samples. Past research has suggested that the extrinsic properties (e.g. size effect, sample-aspect ratios, and experimental constraints) strongly influence the flow stress of small-scale samples. While these studies have furthered our understanding of the complexity of material behavior at the small length scale, they have also raised a recurring question on the maturity of SSMT for engineering applications. Currently, SSMT is unable to directly extract macroscopic-like strain hardening behavior, necking behavior, uniform elongation, and total elongation values in small scale samples. This inability to reliably extract basic mechanical behaviors, representative of macroscopic properties, has stalled the full adoption of SSMT for engineering applications. Our work has successfully addressed this long-standing challenge by introducing an experimental and theoretical approach that enables macroscopic-like deformation at the micro scale. |
