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 ...

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 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 ...

Finite Element Simulation of the Small Punch Test
2014In this paper influence of several key test parameters on SPT results are studied using FEM model. Small punch test (SPT) is based on testing tiny disks by means of continuous loading with a spherical indenter. Small Punch Test is used for definition of some mechanical characteristics: yielding stress and ultimate stress ; fracture toughness.
