Small punch testing of P91 steel
International Journal of Pressure Vessels and Piping, 2006Abstract Results of small punch tests on miniaturized thin discs of P91 steel are compared with relevant conventional tests on bulk specimens. Small punch tests under constant displacement rate were performed at room temperature and 873 K. The results were correlated with results of conventional stress–strain tests. Results of small punch tests under

Punch card output in a small laboratory
Computers and Biomedical Research, 1968Abstract A design is presented for the modification of an IBM 026 keypunch to provide punch card output for a small laboratory computer. Functional interfaces based on this design have been built for the LINC and CAT computers. Circuits, timing diagram, punch codes, and a test program are provided.

Fracture Toughness by Small Punch Testing
Journal of Testing and Evaluation, 1995Abstract The small punch test, currently being used to empirically estimate the material fracture appearance transition temperature (FATT) of a range of components in fossil power plant service, has been further developed for direct estimation of KIc and JIc in a manner that is analytical, material-independent, and requires no prior ...

The viroid: big punch in a small package
Trends in Microbiology, 1993Although viroids consist solely of short lengths of unencapsidated single-stranded circular RNA, they replicate autonomously in plants and cause diseases that are as varied and often as severe as those caused by plant viruses. All this, without ever serving as mRNAs.

Computational Simulation of Small Punch Test
Applied Mechanics and Materials, 2012The paper deals with numerical simulation of Small Punch Test (SPT). SPT is a penetration test used to determine basic mechanical properties from a tiny piece of material. The testing procedure drew a great interest in the last decade, nevertheless there are no generally accepted standards for this type of testing until now.

Small Punch Creep Test: An Overview
Metals and Materials International, 2020Small punch creep (SPC) test has an important role in the remaining life calculation of in-service components functioning at high temperature and harsh ambience. Since the extraction of conventional full scale specimens from the components in service impairs its integrity, SPC test can be used as an alternative technique. This test method requires very

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.

Small punch creep in Fe28Al3Cr0.02Ce alloy
Intermetallics, 2004Abstract Small punch testing of Fe3Al-based intermetallic alloy with Cr, Mn and Ce additions was performed in temperature range 773–873 K. It is shown that the testing procedure enables to study the creep properties of the alloy. The time dependence of the central deflection resembles creep curves observed in conventional uniaxial creep testing and ...
