摘要：

A method of measuring the change in specimen cross section in inhomogeneous deformation is described. A continuous measure of the specimen diameter over the whole specimen gauge length is obtained provided the object is small and has a smoothly changing cross section. The sum of two transducer outputs allows a plot of the specimen profile to be made. Diameter change can be measured over 0·2 in with a maximum resolution of better than 10 μin.
