摘要：
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: the A-VBAR formulation and the HBAR or TBAR formulation, are applied to model the problems. Reasonable agreement between calculated and some preliminary experimental results is achieved. A hypothesis, based on the physical model, is presented. It explains RFEC signals from axially aligned cracks and makes some predictions of possible features for future verification.
