Application of Degenerated Hexahedral Whitney Elements in the Modeling of NDT Induction Thermography of Laminated CFRP Composite

In this paper, degenerated hexahedral Whitney elements are used to model carbon-fiber-reinforced polymer composites in nondestructive testing induction thermography technique. These elements avoid meshing the thin regions of composite and consider the anisotropic multilayer characteristic of the materials and also the flaws inside their volume. The eddy-current problem is solved using A - Φ formulation. The accuracy of this method is shown by comparison with the classical hexahedral elements.
