Abstract Scope |
The NIST AM Benchmark series provide the community with high quality datasets in the form of “challenges” for modelers where selected data is temporarily withheld to enable the comparison of blind predictions. In the 2022 cycle, two tensile deformation challenges were posed: one to predict orientation and scan-strategy dependance of mechanical properties of interest such as Young’s modulus and stress at different points in strain in continuum-scale specimens, and the other to predict microscale (sub-continuum) deformation behavior and fracture location of a single thoroughly characterized specimen given EBSD of one surface and 3D X-ray CT data of the full specimen, and EBSD of a nearby perpendicular plane. This talk summarizes the experimental efforts, data created, and overall findings of the blinded prediction efforts (fully anonymized). We will also ask for audience feedback regarding the Benchmark challenges and discuss potential future challenges that could be developed. |
