Authors: Neerajkumar Wayzode, Vinod B. Suryawanshi
Abstract: Nanomaterials due to their unique mechanical properties; are extensively researched as possible reinforcement in various polymeric materials. Experimental methods of understanding the effect of nano-reinforcement on mechanical properties of the polymeric materials; however, are time consuming and costly. In this research, a numerical simulation model based on finite element approach is developed for prediction of tensile mechanical properties of nano-reinforced polymers. A representative volume element (RVE) model thus developed consists of a two-dimensional finite element model with randomly dispersed circular inclusions of varying size. A Visual Basic for Applications (VBA) code is used to generate a random pattern of the nanoparticles of different sizes. The output of the VBA code is used as an input to commercial finite element software for automatically generating the 2D finite element model. The validation of simulation model is carried out by comparing results of nanosilica/epoxy nonocomposites computed using the program with that of the analytical models. It is observed that the simulation models agree very well with the analytical results.
