Contribution of austenite-martensite transformation to deformability of advanced high strength steels: From atomistic mechanisms to microstructural response
TL;DR: In this paper, the authors analyzed the mechanical response of the atomistic fcc/bcc interface under shear loading and showed that the interface motion follows a Schmid-type law for resolved shear stresses in the transformation direction.

Fast parallel algorithms for short-range molecular dynamics
TL;DR: In this article, three parallel algorithms for classical molecular dynamics are presented, which can be implemented on any distributed-memory parallel machine which allows for message-passing of data between independently executing processors.
