Ideal Strength of Hexagonal Diamond and Related B-C-N Compounds

ORAL

Abstract

We have performed first principles calculations on the ideal strength of h-diamond, w-BN, and $\Phi$- BC$_2$N. We have considered structural deformation under pure tensile, pure shear or biaxial stress fields. The calculated results reveal new atomistic fracture mechanism for these materials.
