Graduate Seminar with Dr. Ashley Spear
Predicting Failure of Additively Manufactured Metals Using Advanced Modeling Techniques
April 8th, 4-5PM, 256 CB
Abstract: Metal additive manufacturing, or 3D printing, offers exciting opportunities to produce complex and intricate structural geometries that would otherwise be difficult or impossible to produce, and to streamline production of new and legacy components for critical structural applications. For these reasons, metal 3D printing has the potential to impact the landscape of many industries, ranging from aerospace to biomedical. With this exciting technology comes an urgent need to understand and predict when, where, and how metal 3D printed parts will fail. This talk will highlight some of the advanced modeling techniques that we have employed recently to examine deformation, fracture, and fatigue of 3D printed metals by accounting for their unique microstructural attributes.
Bio: Dr. Ashley Spear is a Presidential Scholar at the University of Utah. She directs the Multiscale Mechanics & Materials Laboratory, which specializes in integrating experiments, physics-based modeling, and data science to examine deformation, fatigue, and fracture in a wide range of materials. Spear received her B.S. in Architectural Engineering from the University of Wyoming and Ph.D. in Civil Engineering from Cornell University.
