The methodology of determining the construction materials' elastic constants is based on the mechanical tests, being mostly tensile tests, of partially loaded specimens (macro-specimens). The elastic constants obtained are applied mainly when a computer-aided modeling structure is used which considerably advanced due to computer techniques development in the last years (to obtain a deeper understanding of occurring phenomena, it is necessary to find out the (j-£ distribution). It is the aim of this article to introduce a original method for a material identification of FEM computing system. The method is based on the two simply experiments and three simply calculations of only three displacements on the simply etalon bar beam. In this case, it is demonstrated how to find material identification which uses finite element method (the Young's modulus of elasticity and Poisson's ratio are determined by this method).
