Multiscale Data Driven Methodology for Accelerating Qualification and Certification of Additively Manufactured Parts
The defects and microstructural features introduced by additive manufacturing (AM) of parts render the material heterogeneous and anisotropic. Consequently, even in a uniaxial coupon test the material experiences a multiaxial state of stress. The traditional building block approach (BBA) for qualification and certification (Q&C) is inadequate to address the heterogeneity and anisotropy in AM parts. To address these issues along with the inherent cost and time needed for Q&C by the BBA, this article presents a multiscale data-driven approach for accelerated Q&C (aQ&C) of AM parts extending the traditional BBA from the macro- to the upper and lower meso- length scales.
