...Audrey Gbaguidi; Sirish Namilae; Daewon Kim The electrical conductivity and percolation onset of graphene-based nanocomposites are studied by varying both planar and transversal aspect ratios of graphene nanoplatelets (GNP) fillers using a three-dimensional stochastic percolation-based model...

... realistic tube aspect ratios. A representative CNT polymer composite conductive path was chosen from a percolation analysis to establish the three-dimensional (3D) computational finite-element (FE) approach. A specialized Maxwell FE formulation with a Fermi-based tunneling resistance was then used to obtain...

...Majid Baniassadi; Akbar Ghazavizadeh; Yves Rémond; Said Ahzi; David Ruch; Hamid Garmestani In this study, a qualitative equivalence between the electrical percolation threshold and the effective thermal conductivity of composites filled with cylindrical nanofillers has been recognized. The two...

...O. S. Orlov; M. J. Worswick; E. Maire; D. J. Lloyd A combined experimental and analytical approach is used to study damage initiation and evolution in three-dimensional second phase particle fields. A three-dimensional formulation of a damage percolation model is developed to predict damage...

... concerning the electric characterization of random mixtures have been drawn. The specific analysis of porous random materials has been performed and largely discussed. Such an analysis leads to the evaluation of the percolation threshold, to the determination of the convergence properties of Poisson’s ratio...

The size effect is associated with elongation of the correlation length that reaches the finite cell size near the percolation limit as is observed in many critical phenomena. Behavior in the athermal case with long spatial...
