The results of a round robin exercise in predicting ductile instability in two compact tension test specimens are presented and analysed. Many techniques were used, both to analyse the given raw data and to analyse the specimen behaviour, and large differences were obtained especially in defining J ‐resistance parameters. Despite these differences there was little scatter in the final result principally because the specimens failed at plastic collapse. It was concluded that all the techniques were broadly satisfactory provided a plastic collapse analysis is performed, either as part of the analysis or independently.
