摘要:
The electric potential produced by the strain field surrounding a dislocation in a piezoelectric crystal was calculated by the ’’exact’’ plane‐strain method. The results are in close agreement with those of the earliest approximate calculation. A major discrepancy between previous calculations has been traced to a sign error in the exact formulation. The most recent approximate calculation is shown to be incorrect in principle.
