Notes:
A load-displacement curve from a small punch test includes several useful informationthat is related to standard test properties such as the tensile property, fracture toughness and ductilebrittletransition temperature. In this study, the empirical relationship between the material propertyfactors in SP curves and the tensile curves has been investigated by comparing test results and finiteelement analysis results. SP and tensile tests and finite element analyses were performed for severalMn-Mo-Ni low alloy steels with different manufacturing processes. It was found that the yield loads(Py) in the SP curves, if they were adequately defined, were linearly related to the yield strength(σ0). The yield loads defined from the intersection point of two lines tangent to the elastic bendingregion and plastic bending region showed a better relation with the yield strength than those fromthe offset line. The slope of the SP curves from the simulation results had a close correlation withthe hardening coefficient and strength constant as well
