Aplikace metody prutového etalonu pro identifikaci materiálových konstant
Original language description
The original method for a material identification method is based on the two simply experiments and three simple calculations of only three displacements on the simple etalon bar beam. This "bar etalon method" used for detetermination of elastic moduli Eand Poisson's ratio _ of Hooke's materials has already been published in [1], [2]. Further, the possibility of its utilization for material properties identification for FE-calculation, which in fact means tuning of these constants by comparison of FE-calculation with some real construction, was described in [3]. Such method allows stepwise identification of Young's modulus of elasticity E of the examined material and following the Poisson's ratio _ can be set, since the functions between measured displacements and both material constants were found and quantified. The etalon bar of circular shape is simple (as regards the manufacturing technology). Two physical experiments are applied to find the both constants E,mí.
