DETERMINATION OF DYNAMIC YOUNG’S MODULUS FOR STEEL ALLOYS

Abstract

This paper presents an inverse problem for determining the dynamic Young’s modulus for steel alloys and its variation with temperature. The theory is based on the Landau-Murnaghan constitutive law coupled with the longitudinal and flexural resonance methods. The results show that the Young’s modulus varies in a complex way with temperature, in agreement with experimental results.
