Metal/Ceramics Interfacial Shear Failure at Critical Strain
The shear response of the metal/ceramic interface is modeled using a Ti-TiN bi-crystal using MEAM potential.
The structure of the interface is studied, and the shear response is also considered by subjecting the bicrystal in to a pure shear loading.
Modeled in MD using Ti-TiN bilayer system, using MEAM potential.
Structure of the Misfit Dislocation Network (MDN) Depends on the Orientation of Ti
Interfacial Shear Failure is Associated with Motion of MDN with Low Shear Strength
DFT Calculations on Coherent Interfaces Provide Confidence to MD Predictions
