摘要: Abstract Finite element modeling can be a useful tool for predicting the behavior of composite materials and arriving at desirable filler contents maximizing mechanical performance. In present study, to corroborate finite analysis results, quantitative information on effect reinforcing polypropylene (PP) with various proportions nanoclay (in range 3–9% by weight) is obtained through experiments; in particular, attention paid Young’s modulus, tensile strength failure strain. Micromechanical combined Monte Carlo simulation have been carried out establish validity procedure accuracy prediction comparing against experimentally determined stiffness moduli nanocomposites. same context, predictions modulus yielded theoretical micromechanics-based models are compared experimental results. Macromechanical was done capture non-linear stress–strain including observed experiments as this deemed more viable analyzing products made nanocomposites applications dynamics.
