In this study, a semi-nondestructive procedure for stress strain curve estimation was developed using instrumented indentation technique. Additionally, to estimate local stress ? strain curve in the welds with mechanical heterogeneity, a relation between spherical indentation size and measuring range of mechanical property was quantified by using finite element analysis of spherical indentation technique. The developed technique was applied to estimate mechanical properties of low alloy steel and its weld...
