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.
