After two online meetings, a hybrid format was used for the first time with a presence part at BAM. A total of 92 participants from industry and research institutes took part, 12 of them in attendance and 80 online. Apparently, online participation in an event of this kind is very attractive, so that this mode will be maintained.
Several guest lectures dealt with special fracture features, their causes and the presentation of fractographic results. Reports were given on the ongoing AiF project on fracture analysis using machine learning and the follow-up project currently being planned. The implementation of a round robin test on traceable length measurement in the SEM was concretely agreed upon.
Fractographic online database
An important topic of the WG Fractography is continuously the extension of the Fractographic Online Database (www.fraktographie.bam.de). Encouragingly, many members of the Fractography WG have meanwhile contributed to the development of the online database, be it in the form of specimens, materials or image material. Therefore, the stock of data has grown further to currently about 4,300 images in about 400 data sets. Interested parties are welcome to obtain reading access by sending an informal e-mail to: fraktographie@bam.de.
Fractographers are again asked to search their archives for examples for the database and, in the case of planned or ongoing projects, to generate additional images from the outset for input into the database. BAM offers to enter imagery into the database and to examine fractures of interest for the purpose of scientific discourse. Source and authorship of samples or data will be gratefully acknowledged.
