Radial distribution functions of dusty plasma particles are calculated by the application of the Langevin dynamics to a system of particles interacting through the Yukawa potential. Proposed numerical model is first validated by the comparison of the numerical results with available experimental data. Both numerically determined and experimental radial distribution functions demonstrate a good coincidence, thus, enabling a calculation of the structural properties of dusty plasma for a wide range of parameters. On the basis of the performed calculations, dependencies of internal energy and excess pressure from the coupling and density parameters are presented (© 2009 WILEY‐VCH Verlag GmbH & Co.
