Small Punch Testing in Creep Conditions
Journal of Testing and Evaluation, 2001Abstract The creep behavior of low-alloy steel was studied using small punch tests under the action of constant force. Disks with a diameter of 8 mm and a thickness of 0.5 mm were pushed against a die with a bore of 4 mm diameter using a ball of 2.5 mm diameter. The time dependence of the central deflection was registered.

Metals and Materials International, 2019
Small Punch Test (SPT) is an evolving small specimen test technique which has the potential to extract the mechanical properties from small volume specimens. This test method is used to determine the in situ mechanical properties of components in service for measuring the structural integrity and residual life.

Characterization of PEEK biomaterials using the small punch test
Journal of the Mechanical Behavior of Biomedical Materials, 2011The small punch test is widely used to characterize the ductility and fracture resistance in metals and ceramics, when only a small volume of material is available. This study was conducted to investigate the suitability of the small punch test for characterizing polyetheretherketone (PEEK) polymeric biomaterials for changes in material grade ...

A Novel Approach to Small Punch Fatigue Testing
Key Engineering Materials, 2017Miniaturised mechanical test approaches are now widely recognised as an established means of obtaining useful mechanical property information from limited material quantities. To date these methods have largely been adopted to characterise the creep, tensile and fracture characteristics of numerous material systems from a range of industrial ...

On the Correlation of Fracture Quantities in Small Punch Test
Key Engineering Materials, 2013Several possible routes are available for estimation of fracture behaviour from the results of small punch tests performed at constant rate of deflection. The routes include: (i) measurement of relevant dimensions directly on ruptured specimens, (ii) determination of critical deflections on the load vs.

Characterisation of Mechanical Properties by Small Punch Test
Key Engineering Materials, 2014The specific desired properties for structures and components working in critical environments (e.g. different structure parts of power plants) require current information about degradation processes coming out in materials. Obtaining of this information by the help of the classical tests of mechanical properties (tensile test, Charpy test, fracture ...

FEM Analysis of Small Punch Tests
Key Engineering Materials, 2017In recent years the small punch test method has become an attractive alternative compared to traditional material testing procedures, especially in cases where only small amounts of material are available. In contrast to standard test methods, the relevant material parameters can not be as simply obtained from the experimental measurements of SPTs ...

Yield Strength Evaluation by Small-Punch Test
Journal of Testing and Evaluation, 2009Abstract Because of the mechanical property degradation experienced by the nuclear power plant components, it is important to evaluate the evolution of the mechanical properties during service, such as the yield strength. A lack of materials available from nuclear power plants has led to the development of more and more small-sized ...

Small Punch Testing on High Chromium Steels
Volume 6B: Materials and Fabrication, 2016The Small Punch test is a miniaturized non-intrusive methodology that allows performing creep tests using very small specimens. It can be used for the residual lifetime assessment of in service components. In the last years, numerous applications of Small Punch Testing as well as related pre-normative work and Round Robin exercises have ...

Influence of Friction on the Response of Small Punch Test
Transactions of the Indian Institute of Metals, 2015Small specimen test techniques are suitable for assessing the current mechanical properties of in-service components using small volume samples compared to conventional tests. Small punch test is a reliable test method for predicting the post-yield response. The effect of lubrication of the punch-specimen interface on the load–displacement response and
