Abstract: The aim of the present study was to determine elastic modulus of the metal-based composites containing different volume fraction of SiC particulates using an innovative free-free beam type impact based technique. This technique is based on classical vibration theory by which the elastic modulus of the sample is determined from the fundamental resonant frequency obtained from the experiment and density determined by the Archimedes principle. In addition, a finite element model is proposed for the determination of dynamic elastic modulus of the composite sample using the first natural frequency corresponding to the flexural mode. Both simulation and experiments were conducted on magnesium based composite due to much interest in the industry. The elastic modulus values obtained using finite element method were found to be in close agreement with the values obtained from the impact based experiments and in better agreement when compared to theoretical methods such as Eshelby and Halpin-Tsai method.
