Material plastic properties characterization by coupling experimental and numerical analysis of small punch beam tests [PDF]
A novel small punch beam testing (SPBT) system consisting of a top die, a bottom die and a flat punch with semi-circular cross-section head has been designed and tested. The specimen is a small beam with rectangular cross-section.

Material plastic properties characterization using a generic algorithm and finite element method modelling of the plane-strain small punch test [PDF]
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

Characterisation of deformation process and fracture mechanisms of P91 steel at 600°C in small punch tensile testing [PDF]
This paper investigates the microstructural evolution and fracture mechanism of the P91 steel during small punch tensile tests. Disc specimens, 8 mm in diameter and 0.5 mm in thickness, were tested in a small punch test rig at 600 °C using a constant ...

Simulation of the small punch creep test with consideration of variation of material properties [PDF]
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

The role of punch eccentricity in small punch testing
The small punch testing technique under quasi-static loading was examined in the view of punch eccentricity role. It might arise especially when the ball is used as the penetrating tool, instead of hemispherical-ended punch. The austenitic stainless steel AISI 316L was chosen to execute several various “large scale” tests in order to calibrate the ...

Review of Characterization on Hydrogen Embrittlement by Micro-Sample Testing Methods
Conventional-sized specimens have been well and widely applied in research on hydrogen embrittlement. However, when the limited-size core components (nozzles and valves, etc.) of hydrogen energy equipment are evaluated for service damage, traditional ...
