Experimental and numerical investigation of small punch creep test [PDF]
, 2015 The small punch creep testing (SPCT) technique has received much attention because it can provide information on the creep behaviour of materials with a very small specimen being tested. However, the nature of the test is complex and several aspects of the behaviour of the specimen, characterised by various non-linear concurrent processes, still need ...

Interpretation of non-conventional miniaturized creep test: derivation of equivalent gauge length
Journal of Materials Research and Technology, 2023 The objective of this paper is to clarify the nature of the equivalent gauge length of miniaturized creep test methods. A mechanics-based approach was employed to allow conventional uniaxial creep data to be obtained from non-conventional miniaturized ...

Simulation of the small punch creep test with consideration of variation of material properties [PDF]
, 2009 A new finite element model of the small punch creep test is described. The material constitutive relationship for creep considered is a simple Norton power law: in this study the exponent in the power law is varied for each element to simulate the random

Thickness of small sample for creep property evaluation of 9Cr steel base metal of piping on site
Nihon Kikai Gakkai ronbunshu, 2022 We had proposed a creep life assessment method for boiler piping that can consider the heat-to-heat variations of the creep properties of each welded joint, where the creep properties of the welded joint are estimated from those of each base metal.

Influence of heat treatment on creep behavior of IN625 coating on a Ni3Al-base superalloy
Materials Research Express, 2021 IN625 coatings applied by selective laser melting show high resistance at high temperatures but the creep behavior of such coatings is not well understood. In this paper, the microstructure and creep behavior of this coating applied to Rene80 alloy under

Material plastic properties characterization using a generic algorithm and finite element method modelling of the plane-strain small punch test [PDF]
, 2010 In this paper, a novel plane strain small punch test (SPT) method is proposed for material plastic properties characterization. The plane strain SPT is different from the standard SPT in the two ways: (a) a long thin rectangular specimen (with dimensions
