"The Qualification Response Envelope and The Scientific Foundation for Designing Additively Manufactured Structural Parts"
Sharlotte Kramer, Sandia National Laboratories, Albuquerque, New Mexico
ABSTRACT Structural components are commonly designed with a minimum safety factor for some specific quantity of interest. The part-to-part variability of additively manufactured (AM) parts challenges this paradigm. To address this, a “qualification response envelope” (QRE), allowing for a range of acceptable mechanical response of the part in a system, could anticipate and tolerate AM variability. The foundation of a QRE is discovering the relationships between mechanical part performance, AM microstructures, material behavior, and component geometry. This seminar describes several Sandia projects on this foundational understanding. SNL is managed and operated by NTESS under DOE NNSA contract DE-NA0003525.
BIOGRAPHY Dr. Sharlotte Kramer received her Ph.D. in Aeronautics from Caltech and was a postdoc at UIUC in Materials Science. For ten years, she has worked at Sandia National Laboratories in the Structural Mechanics Laboratory, where she is principal investigator of interdisciplinary projects at the intersection of solid mechanics, material science, computer science, and data science. Her areas of interest are in-situ full-field optical measurements for mechanics of materials and failure, ductile failure, mechanics of joints and welds, polymer foam mechanics, mechanics of additively manufactured metals, inverse methods for constitutive model identification, and machine learning for mechanics of materials.
