Abstract
The present paper investigates Electrical Resistance Change Method (ERCM) for thick CFRP laminates with a dent The authors have proposed the damage identification method for CFRP using thc ERCM and confirmed its applicability for beams and thin plate-type specimens in the previous studies. However, the dent is made for thick CFRP and the dent causes electrical resistance decreases. In the present study, we focus on the dent and the electrical resistance decrease is adopted for monitoring delamination location. FEM analyses are used to obtain electrical resistance decrease distributions. Response surfaces are adopted to estimate the delamination location here. The results show good agreements with the experimental data.
