Abstract in different language:	Nowadays, additive technology is modern and high technology for manufacturing of complex bodies with advanced properties and various and complicated shapes, where conventional technologies are not possible to use. Applications of 3D printing technologies of metals can be found in mechanical, biomechanical or aerospace engineering. For that reason, understanding to wave processes in heterogeneous, layered and functionally graded materials is important issue for this time. In this contribution, an explicit local time stepping scheme for modelling of discontinuous wave propagation problems in heterogeneous bars by the finite element method is used based on work. In this method, the local stepping algorithm with respect to local wave speed and local stability condition at each material point is employed. The accurate modelling of discontinuous wave propagation in elastic heterogeneous bodies is still an open problem in numerical methods. Wave propagation problems in graded elastic bars has been studied. Numerical methods currently used comprise the finite volume method, higher order discontinuous Galerkin formulation, the graded finite element method and etc.
