The development of procedures for impact testing

Abstract

This report provides a broad overview of the progress in procedural improvements for impact testing. It includes a short summary of early developments, a discussion of topics that have been the subject of recent research, and a description of the importance of direct and indirect verification procedures. The need for standard procedures was recognized soon after the test was developed, and the early discoveries help to build the framework for our current procedures. Nevertheless, even after all these years of procedure development, researchers still find the need to learn more about certain aspects of the test procedures. Recent research seems to be concentrated in several broad categories: the specimen (e.g. surface finish, tolerances, and miniature sizes for special applications), the anvils and striker (e.g., radii and surface finish), and general test procedures (e.g. time to reach test temperature and suitability for cryogenic testing).
