Different compositions of the layered bar are assumed as well as number of layers and different materials. The effect of bar composition on stress distribution is analyzed. For numerical simulations, the finite element method and the finite volume method are used in the sense of explicit time integration. Numerical computations show the strong influence of layer compositions on the dispersion of a pulse and stress distribution in a heterogeneous bar. The numerical prediction of stress wave propagation in heterogeneous bars helps for the setting of suitable experimental specimens made by additive technologies for studies of wave propagation in such materials.
