    A What is Exponent b in Voltage-to-Area Flaw Relationships?

    I initially suspect b ~ ( t / d)^3 where t relates to thickness and d is skin depth at the frequency and conductivity.

    A What is Exponent b in Voltage-to-Area Flaw Relationships?

    Hi Berkerman, This is motivated by the need to estimate flaw depths and assess risks due to improper acceptance thresholds. Eddy current testing is a method gaining momentum in aerospace applications as a faster, cheaper, safer option for replacing radiography as a dominant method of volumetric...

    A What is Exponent b in Voltage-to-Area Flaw Relationships?

    [Mentor Note: Additional information has been added to this OP to address questions asked in subsequent replies below] I'm analyzing the relationship between induced voltage (V) and semicircular area (A) in a conductive flat plate with notches in a fixed alternating magnetic field, specifically...
