Retraction: Failure Analysis of Drive Axle Shaft failed under Torsional Stress (IOP Conf. Ser.: Mater. Sci. Eng. 1128 012011)

This article has been retracted by IOP Publishing following an allegation that the work used three images from A V Guimaraes et al [1] without attribution. IOP Publishing has investigated in line with the COPE guidelines, and agrees that the following figures have been reused from A V Guimaraes et al without attribution: Figure 10 (Figure 8 in A V Guimaraes et al) Figure 11 (Figure 5 in A V Guimaraes et al) Figure 12 (Figure 6 in A V Guimaraes et al) Figure 13 (Figure 7 in A V Guimaraes et al) The evidence gathered by IOP Publishing to date, combined with the lack of author response, considerably reduces confidence in the work to the extent that IOP Publishing has made the decision to retract the work. We would welcome receiving their account of events. IOP Publishing wishes to credit the anonymous whistleblower for bringing the issue to our attention. The authors have not agreed or disagreed to this retraction and we would welcome their version of events.
