Abstract
MOC(Method of Cell) is a new method of investigating wave propagating in material with periodic microstructure, and can reflect the effect of microstructure. In fact, by this theory, the actual composite can be transformed into a homogeneous higher order continuum with microstructure. Wave propagation in periodically bilaminated medium consisting of linearly elastic layers can be treated as a special application of this method. In this paper, it was used to simulate the dynamic response of carbon-phenolic to impulsive loading under certain boundary conditions. From the comparison between the results obtained from this method and the exact results based on propagator matrix theory, excellent agreement is achieved. Conclusion can be made that the oscillation periodicity is decided by the thickness of unit representative cell within the elastic limits of both sublayers.
