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

A Direct Methodology for Small Punch Creep Test
Experimental Mechanics, 2015Small punch creep test (SPCT) has strong advantages in practice compared with traditional uniaxial creep test because a small sheet specimen (10 × 10 × 0.5 mm) can be obtained from in-service facilities or mechanical components without damage. In this paper, a novel investigation is proposed to directly interpret SPCT results in consideration of ...

Small Punch Testing for Creep: Progress in Europe
Volume 9: Eighth International Conference on Creep and Fatigue at Elevated Temperatures, 2007The small punch or disk bend test has particular value in life prediction of operating equipment since the test requires very small amounts of material (a common test specimen disk is 0.5 mm thick with a diameter of 6 to 10 mm), and usually the required volume of material can be acquired from operating equipment in a virtually nondestructive manner ...

Development of Small Punch Test for EAC Evaluation
Key Engineering Materials, 2005We are developing a Small-Punch SCC testing apparatus with an in-situ observation system applied to high temperature water and high pressure. This new testing apparatus is used to evaluate the Environmentally Assisted Cracking effect. A constant loading rate was carried out with different values of speed, of water flow rate and different polishing of ...

Evaluation and Optimisation of the Small Ring Test and its Amalgamation with the Small Punch Test
2023This thesis explores the limitations of conventional mechanical testing methods and assesses two miniaturised specimen testing techniques: the small ring test (SRT) and the small punch test (SPT). Given the nascency of the SRT, especially as a tensile test, this thesis rigorously assesses the SRT for 48 pin displacement rates on Stainless Steel (Grade ...

Influence of Oxidation to Small Punch Creep Test
Key Engineering Materials, 2007In order to validate a procedure for creep rupture tests using small punch specimens, the influences of oxidation on the creep deflection curve, rupture time and ductility of miniature specimens were investigated. Using disc test specimens of 10mm in diameter and 0.5mm in thickness, a variety of small punch creep (SPC) tests for Cr5Mo steel at the ...
