| Popis: | An intended numerical investigation is carried out. The results indicate that, even if a perfect adhesive bond is preserved between the particles and matrix materials, the two-phase element cell model is unable to predict the strength increment of the particulate polymeric composites (PPC). To explore the main reinforcing mechanism, additional microscopic experiment is performed. An "influence zone" was observed around each particle which is measured about 2 to 10 micrometers in thickness for a glasspolyethylene mixture. Then, an improved computational model is presented to include the "influence zone" effect and several mechanical behaviors of PPC are well simulated through this new model. |
