“…The development of small-scale mechanical testing techniques as the alternative of conventional largescale testing was mainly driven by the need to measure mechanical properties at smaller length scales owing to increasing device miniaturization, as well as the need for microstructure design from the physical point of view. 10 Particularly, the need for testing irradiated materials in a limited volume to minimize the radiation dose directly led to the development of small-specimen test technology and standards. 8,11,12,13 Instead of using the uniaxial tensile method, the Brazilian disc compression method uses compression load to create tensile stress in the disc.…”

“…Standard durability tests always involve large material losses, as they require relatively large samples. Therefore, in case of novel materials, it becomes very convenient to use micro-samples for testing, which are often obtained directly from the element during its working time [1,2,3,4].…”

Nowadays, various small specimen test techniques have gained wide popularity and appreciation among researchers as they offer undoubtful benefits in terms of structural material characterisation. This paper focuses on small punch tests (SPTs) performed on small-sized disc specimens to assess the mechanical properties of 14Cr oxide dispersion strengthened (ODS) steel. A numerical model was established to support experimental data and gain deeper insight into complex strain states developing in a deformed specimen. Modern evaluation procedures were discussed for obtaining mechanical properties from the small punch force-deflection response and were compared with the literature. Applicability and universality of those relations at different test conditions were also studied. It appeared that different ball diameters used had negligible influence on yield point but strongly affected ultimate strength estimation. It was found that friction belongs to decisive factors determining strain distribution in samples, as dry conditions increase the peak strain and move its location farther from the punch pole.
