Digital Twins: An enabler for digital transformation
, 2021 Digital Twins are a virtual representation of anything of value for an organization that create a link between the real and virtual worlds by a continuous bidirectional data/information exchange. In this chapter we present the origins of the concept and how it evolved with the advent of new technological trends.

Twin migration in Fe-based bcc crystals: Theory and experiments [PDF]
, 2014 We establish an overall energy expression to determine the twin migration stress in bcc metals. Twin migration succeeds twin nucleation often after a load drop, and a model to establish twin migration stress is of paramount importance.
