Is Osmium Diboride An Ultra-Hard Material?

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...
