Abstract
A technique has been developed in which transient potential drop signals are obtained during initial and anhysteretic magnetisation. From these, a deviation curve can be obtained that reflects the absolute stress not only in small test specimens, but also in large steel structures. However, further investigations and experimental work are required before an instrument for reliable measurement can be of practical value. The use of deviation curves to indicate structural changes during fatigue, before cracks develop, may also be a possible application of the new technique.
