| Numerical calculations are made of theoretical strength and range of stability of a perfect uniaxially stressed crystal lattice of bcc vanadium, niobium and tantalum in the framework of extended generalised exponential potential by applying Born stability criteria. Two ranges of stability, a bcc phase and a body centered tetragonal phase are found to exist. The computed values of theoretical strength and strain of bcc V, Nb and Ta agree reasonably well with the experimental limits. |
