The paper summarizes capabilities of the small punch tests on miniature disc specimens from metallic materials. Results obtained by small punch tests can be correlated with mechanical properties determined by conventional or other miniature tests. Three basic types of small punch test setup: i) static/fracture, ii) creep and iii) stress relaxation are described and the basic quantities that can be obtained are shown. Relations for an assessment of conventional mechanical properties from quantities obtained by small punch test are presented.

Abstract The elastic and large deformation mechanical behavior of four materials with known clinical performance was examined and correlated with the wear behavior in a hip simulator. Acetabular liners of a commercially-available design were machined from UHMWPE, HDPE, PTFE, and polyacetal and wear tested in a multidirectional hip joint simulator. Elastic and large-deformation mechanical behavior was directly measured from the wear-tested liners using the small punch test. The inverse finite element method was used to compute elastic modulus from the measured small punch test initial stiffness, and the contact stress for the liners was calculated using the theory of elasticity solution. Positive, statistically-significant correlations were observed between the hip simulator wear rate and the initial peak load, ultimate load, and work to failure from the small punch test. Negative correlations were observed between the wear rate and the elastic modulus and contact stress. This results of this study support the hypothesis that the large deformation mechanical behavior of a polymer plays a greater role in the wear mechanisms prevalent in total hip replacements than the elastic behavior.

The development and practical use of the Small Punch test technique for the evaluation of mechanical properties of metallic materials in Europe resulted in the publication of the CEN document CWA 15627 Small Punch Test Method for Metallic Materials in 2007. The evaluation of the actual mechanical properties of metallic materials from the results of such tests according to CWA 15627 were presented at the first three International conferences SSTT "Determination of Mechanical Properties by Small Punch and other Miniature Testing Techniques" held in Ostrava (2010, 2012) and Castle Seggau in Austria (2014). In the present paper the motivation and the steps taken to lead to the setting up of a working group and programme facilitating the transformation of CWA 15627 Small Punch Test Method for Metallic Materials into an EN standard are summarized along with early results of the programme.
