This dataset contains data obtained along the validation of the multi-family variant of the cluster model for thermoelastic composites with quasi-random particle arrangement. The model has been presented in the forthcoming publication. In this paper also the numerical algorithm for the model implementations is described. This publication is currently under revision, being submitted to the journal Continuum Mechanics and Thermodynamics. The model was validated by performing simulations for two-phase composites, either reinforced by ceramic inclusions or weakened by voids, with mechanical properties included in Table 1 of related publication. 30 random arrangments of 50 inclusions in the representative unit cell were generated and analyzed, which differ by mean minimum distance between the inclusions. The parameter is one of factors which may describe particle clustering. Validation was performed with respect to the own reference calculations performed on unit cells by finite element method. The effective stiffness tensor for the sample and the mean strain or stress within each individual inclusion were aquired in the computations. The calculations have been performed with the Wolfram Mathematica as concerns mean-field cluster model and by AceFEM in case of full-field analyses.
