Abstract:
A load-displacement curve from a small punch test includes several useful information
that is related to standard test properties such as the tensile property, fracture toughness and ductilebrittle transition temperature. In this study, the empirical relationship between the material property
factors in SP curves and the tensile curves has been investigated by comparing test results and finite element analysis results. SP and tensile tests and finite element analyses were performed for several
Mn-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 bending region and plastic bending region showed a better relation with the yield strength than those from
the offset line. The slope of the SP curves from the simulation results had a close correlation with the hardening coefficient and strength constant as well.
