Abstract: MOC (method of cell) is a new means of investigating the problem of wave propagation in materials with complex interior unit structure. The MOC can be used to investigate transient waves due to pulse loading as well as harmonic waves. MOC was introduced, then, it was used to simulate the problem of material dynamic responses in order to review the reliability of MOC. Comparison was made between the results obtained from this method and those from propagation matrix technique. The results from MOC are of high accuracy and MOC is easier to program than traditional difference method and finite-element method.
