Abstract
A simplified physical model for two-dimensional (2-D) finite element analysis of axially aligned crack responses for the remote field eddy current (RFEC) technique is proposed. Two formulations are applied to model the problems. Reasonable agreement between calculated results and some preliminary experimental results is achieved. A hypothesis, based on the physical model, is presented. It explains the RFEC signals from axially aligned cracks and makes some predictions of possible features for future verification
