Modified Fourier solution for diffusion governing law applied to blister formation and development

This paper discusses about the equation derivation using paper and pencil approach. Further, using commercial softwares of Mathematica™ and Abaqus™, analytical and numerical approaches are developed to simulate the ionic transport needed to induce pressure that eventually causes the blister to propagate. The principle is useful not only for organic coating problem, but also for other materials involving delamination phenomena including other sophisticated surface engineering methods.
