ABSTRACT

X-ray micro-computed tomography provides significant opportunities for understanding the evolution of complex materials at full volume and high resolution. Of particular importance is the role that material structure plays in terms of the relative effects on localized material straining during the deformation process. In this talk, we will discuss the use of X-ray tomography to understand material failure in various solids including open cell lattices/foams, additively manufactured microstructure, and granular assemblies. In each of these material cases, analyses of the in situ data using digital volume correlation and advanced morphological segmentation methods are shown to provide useful information regarding the role of local material structure on the nature of failure. The role of various experimental in situ testing parameters on the underlying measurement uncertainty will also be discussed.

BIOGRAPHY

Dr. Christopher Saldaña is the Ring Family Professor and an associate professor of mechanical engineering at Georgia Tech. He previously held the Harold and Inge Marcus Career Development Professorship at the Department of Industrial and Manufacturing Engineering at Penn State. Dr. Saldana’s research has focused on developing integrated frameworks for describing relationships between processing, structure and properties for advanced manufacturing operations. He is an expert on materials processing and nondestructive evaluation with 15 years of experience in the precision manufacturing sector and a focus on multi-scale materials and metrology characterization for supporting new product development and realization of next generation manufacturing processes. His current work is focused on developing process qualification and process design tools for hybrid additive/subtractive manufacturing and digitally-enabled manufacturing. He earned his graduate and undergraduate degrees from Purdue and Virginia Tech, respectively, and has been recognized with several awards, including an NSF CAREER award, the Robert J. Hocken SME Outstanding Young Manufacturing Engineer award and an R&D100 Technology Award.
