| Sumario: | The article describes calculations of ideal tensile and shear strength of OB. Density functional theory calculations of ideal strength, which is defined as the peak stress in the stress-strain curve in the weakest tensile stretch or shear slip direction, have been developed to determine the critical stress at which a perfect lattice becomes unstable under deformation strain. |
