NIST Software Package for Obtaining Charpy Transition Curves

May 11, 2021
Author(s)
Enrico Lucon, Jolene D. Splett, Amanda Koepke, David Newton
NIST has developed a software package that allows users to fit test results obtained from Charpy or toughness tests as a function of test temperature, thereby obtaining so-called transition curves. Non-linear fitting is available for five regression models

Carlos R. Beauchamp, Johanna Camara, Jennifer Carney, Steven J. Choquette, Kenneth D. Cole, Paul C. DeRose, David L. Duewer, Michael Epstein, Margaret C. Kline, Katrice Lippa, Enrico Lucon, Karen W. Phinney, Maria Polakoski, Antonio Possolo, Katherine E. Sharpless, John R. Sieber, Blaza Toman, Michael R. Winchester, Donald Windover
The National Institute of Standards and Technology (NIST), formerly the National Bureau of Standards, was established by the U.S. Congress in 1901 and charged with establishing a measurement foundation to facilitate U.S. and international commerce. NIST

Charpy Instrumented Test Suite and User's Manual

July 9, 2020
Author(s)
Damian Lauria, Enrico Lucon, Felipe Baldner
The NIST Instrumented Charpy Test Suite is a set of standalone programs intended to allow anyone with appropriate hardware to perform and analyze instrumented Charpy impact tests. The software is provided in both raw code and executable formats with an

Influence of Machine Anvil Wear on Charpy Test Results

May 12, 2020
Author(s)
Enrico Lucon, Raymond L. Santoyo
We investigated the influence of the state of wear of Charpy machine anvils on test results by performing impact tests on NIST specimens of three energy levels with a machine equipped with new anvils (compliant with both ASTM E23 [1] and ISO 148-2 [2]) and

Development and Validation of Small Punch Testing at NIST

April 16, 2020
Author(s)
Enrico Lucon, Jake T. Benzing, Nikolas W. Hrabe
Small Punch (SP) testing is a methodology that uses tiny disks (generally 8 mm in diameter and 0.5 mm thick) to estimate mechanical properties of metallic materials, such as tensile properties, fracture toughness, and ductile-to-brittle transition

NIST Instrumented Charpy Analysis Software (NICAS) - User's Manual

April 15, 2020
Author(s)
Damian S. Lauria, Enrico Lucon
The NIST Instrumented Charpy Analysis Software (NICAS) is a standalone LabVIEW program that can be used to analyze instrumented impact tests in accordance with the following international test standards: ASTM E2298-18 [1] and ISO 14556:2015 [2]. It is also

Design Considerations to Improve Charpy Instrumented Strikers

March 16, 2020
Author(s)
Nicholas Vlajic, Akobuije Chijioke, Enrico Lucon
Instrumented impact testing allows the applicability of conventional Charpy tests to be extended toward assessing mechanical properties such as dynamic fracture toughness and dynamic tensile properties. In this work, we present design considerations for
