The effect of plasticity on the ability of the deep hole drilling technique to measure axisymmetric residual stress

University of Bristol is a world-leader in measurement of residual stress in highly-stressed engineering components, particularly in relation to operation of nuclear power plant. Paper shows that in highly-stressed components, measurement can induce plasticity and previous method of interpreting result is incorrect. However, work also demonstrates that plasticity can be correctly accounted for. Work led to ~£200k of direct industrial funding from Rolls-Royce plc. [contact: Stress Engineer] and ~£750k from EDF Energy [contact: High Temperature Specialist, Assessment Technology Group]. There has been technology transfer via Veqter Ltd. [REF3b: Veqter; contact: Managing Director]. Work is identified as research group highlight in REF5.
