Industry Partners: PRI
Objectives:
-
To develop a finite element code for simulating the eddy current MOI inspection geometry for use in inspection/equipment optimization
-
To work with the industrial partner in the validation and application of the MOI inspection model
Approach:
- Provide understanding
of effect of layer thickness and air gaps between layers of MOI response
- Use model as experimental
testbed for parametric studies varying bias fields, frequency, excitation
level, industrial foil thickness as function of defect type/size
- Use prediction
of magnetic fields to optimize imaging process
- Validate the model in cooperation with industry partners
MOI is applicalbe
to detection of corrosion and second layer cracking with large coverage
area and easy-to-interpret imagesl. A numeriral model for siulating
physical processes help make informed design decisions.
Products:
- Model predictions
for understanding the physics of field/flaw interactions
- Results transferred
to PRI for use in design of next generation MOI instruments
