  • Abstract The effect of weight fraction on the tensile behavior of the polymethylmethacrylate (PMMA) with mixing silver nanoparticles (PMMA/AgNPs) was investigated using molecular dynamics simulation (MD). The mechanical properties of PMMA/AgNPs were calculated and analyzed at different weight fraction of AgNPs (0.60 wt%, and 1.77 wt%) and different temperature which corresponding room temperature, melting point (400K) and molten phase (550K). After adding AgNPs into PMMA, the Young’s modulus, and tensile strength of PMMA were greatly increased with weight fraction rising indicating that the AgNPs enhanced its mechanical properties. However, at high temperature, the Young’s modulus of both the PMMA and the PMMA /AgNPs exhibited significantly reduced from room temperature to high temperature, as the mechanical properties of PMMA /AgNPs were primarily dominated by temperature.
