Retrospective Account

Abstract Throughout his career, Zbib was innovative, originating models in seminal papers that anticipated areas of subsequent increased interest. These include strain-gradient plasticity, discrete dislocation dynamics, multiscale modeling, Arrays of Somigliana ring dislocations, and nanoscale plasticity. We comment here on these aspects of his work. Many of the papers in this volume represent applications of these ideas.
