Existence and stability of a screw dislocation under anti-plane deformation [PDF]
, 2014 We formulate a variational model for a geometrically necessary screw dislocation in an anti-plane lattice model at zero temperature. Invariance of the energy functional under lattice symmetries renders the problem non-coercive.

Model for the hardness-depth relationships of ion-irradiated nanocrystalline metals
Journal of Materials Research and Technology, 2023 In this work, a mechanistic model is proposed for ion-irradiated nanocrystalline (NC) metals to characterize the evolution of hardness as a function of the indentation depth at room temperature and under quasi-static loading condition. At the grain level,

Back stress in strain hardening of carbon nanotube/aluminum composites
Materials Research Letters, 2018 As demonstrated by the loading–unloading tests and the modeling of the grain size effect and the composite effect, mainly owing to the back stress induced by CNTs, carbon nanotube/aluminum (CNT/Al) composites exhibit higher strain hardening capability ...
