The purpose of this paper is to conform an available material data for aluminum alloy material (P A11). This task was filled with the aid of computer modeling techniques, which are based on Finite Element Method (FEM), and our own experimental tests of quasistatic tension/compression material samples. For this kind of research FEM is most commonly used, but there are also other numerical methods that can be applied. The idea of FEM is the division of the given continuous area into a finite number of subareas (finite elements) connected with one another in nodal points and approximation of solution inside the finite elements using interpolation functions and function values in nodes. Numerical analysis was performed with the LS-Dyna commercial software. Reconstruction of conditions of experiment required application of implicit method of numerical integration in time, so called implicit solver. At this stage of work the aluminum alloy P A11 with respect to Johnson-Cook model was researched. A further work for fmding a good material data for WHA, U12A steel for other constitutive models will be performed. A good agreement of the numerical and experimental results is received. Other material data used in modeling, which were not determined by experiment, assumed according to literature sources.
