Estimation of mechanical properties of metallic materials using inverse method in SPT

ABSTRACT Mechanical characterization of metallic materials by Small Punch Test (SPT) allows to evaluate uniaxial tensile properties [1]. In this work, by means of an inverse procedure and numerical simulation of SPT tests we estimate uniaxial tensile properties of AISI 304L stainless steel. We detail the applied procedure to estimate the yield stress where the two parameter Hollomon relation is assumed as a constitutive relationship. According to the obtained results, it can be suggested that the developed procedure is suitable for estimating properties in metallic materials, if a suitable constitutive equation is used.
