Advisors: David L. McDowell, Ting Zhu, Chaitanya S. Deo, Laurent Capolungo, Surya Kalidindi, Josh KacherMetal plasticity is a multiscale phenomenon that is manifested by irreversible microstructure rearrangement associated with nucleation, multiplication, interaction, and migration of...
Characterization of Multiscale Porosity in Cement-Based Materials: Effects of Flaw Morphology on Material Response Across Size and Time Scales
28 Jun 2016 | Contributor(s):: Mayercsik, Nathan Paul
Advisors: Kimberly E. Kurtis, Chloe Arson, Arun M. Gokhale, Laurence J. Jacobs, Lori L. Graham-BradyIt is perhaps paradoxical that many material properties arise from the absence of material rather than the presence of it. For example, the strength, stiffness, and toughness of a concrete are...
Atomistic and Multiscale Modeling of Plasticity in Irradiated Metals
12 Jan 2015 | Contributor(s):: Narayanan, Sankar
Advisors: Ting Zhu, Chaitanya Deo, Hamid Garmestani, David L. McDowellIrradiation induces a high concentration of defects in the structural materials of nuclear reactors, which are typically of body-centered cubic Iron (BCC Fe) and its alloys. The primary effect of irradiation is hardening which...
Prediction of Material Fracture Toughness as Function of Microstructure
12 Jan 2015 | Contributor(s):: Li, Yan
Advisors: Min Zhou, David L. McDowell, Richard Neu, Ting Zhu, Shuman Xia, Donald ShihMicrostructure determines fracture toughness of materials through the activation of different fracture mechanisms. To tailor the fracture toughness through microstructure design, it is important to establish...
