The universal equation of state of solids (UEOS) proposed by Vinet is applied to analysis of EOS data for Mo and W in literature obtained experimentally and by ab initio theoretical calculations reported by different groups. It is demonstrated that the experimental measurements and theoretical calculations are consistent with each other and UEOS is a good analytical expression of EOS for solid Mo and W. The bulk modulus and thermo-expansion coefficients calculated from EOS analysis for Mo and W are in agreement with values obtained by direct measurements with other techniques with high accuracy.
