摘      要：This work proposes to study the effective elastic properties(EEP)of a wood-plastic composite(WPC)made from polyethylene terephthalate(PET)and Chilean Radiate pine’s wood our,using nite element simulations of a representative volume element(RVE)with periodic boundary *** are validated through a static 3-point bending test,with specimens obtained by extruding and *** effect of different weight fractions,space orientations and sizes of particles are here *** predictions are empirically conrmed in the sense that composites with more wood our content and bigger size,have higher elastic ***,these results are very sensitive to the orientation of *** and Reuss mean-eld homogenisation approaches are also given as upper and lower *** tests evidence that exural strengths and ultimate tensile elongations decrease respect to 100%PET,but these properties can be enhanced considering particle-size distributions instead of a xed size of wood our.
