| Abstract Scope |
Rob Wagoner’s impactful career spanned plasticity, constitutive theory, metal forming,defect interactions, and beyond, and it continues to provide inspiration for researchersacross materials science, metallurgy, mechanics, and computational science. Rob cast anequally large shadow in his personal life, and was admired by his many friends and hisloving family – and I was fortunate to have known him as my father-in-law. In this talk, I willpresent recent work from my group on mechanics and dislocation theory in electronic andquantum materials, including studies of new types of dislocations in 2D materials. These defects include moiré superlattices as examples of dislocation arrays in bilayers; interfacemisfit dislocations in 2D material heterostructures; and out-of-plane screw dislocations in2D material layers. Some of the underlying concepts in these quantum materials mirror topics from Rob’s highly impactful research, including the need to understand and quantify out-of-plane deformation in plastically deforming sheets, and the importance of understanding active slip systems in bicrystals. Indeed, Rob’s work has inspired many of us who study defects and deformation in materials. For me, these common interests were the topic of many enjoyable conversations with Rob during our family time over the years. |
