Spreadsheet-Based Software for the Analysis of Unloading Compliance Fracture Toughness Tests in Accordance with ASTM E1820

Published

Author(s)

Enrico Lucon

Abstract

NIST has developed a user-friendly spreadsheet-based software for the analysis of elastic-plastic fracture toughness tests conducted according to ASTM E1820-20b on either Compact Tension or Single-Edge Bend specimens using the Unloading/Elastic Compliance (UC/EC) single-specimen technique. The software consists of multiple spreadsheets, which feature several macros that automatize most calculations. Complete user's instructions are provided in this report. The software has been successfully validated using nine sample data sets that are available through ASTM, covering both specimen configurations and various fracture toughness levels. As in the case of previous software packages developed by the Fatigue and Fracture Group of NIST Boulder, the spreadsheet will be made freely available to the public by contacting the author of this report.
