Dissolution Driven Fracture - Simulation of Crack Growth

The growth of a crack subjected to corrosion fatigue is studied using adaptive finite elements.The crack growth is the result of a repeated cycle of dissolution of the material, formation of a protectiveoxide film and break-down of the oxide film due to straining at the surface. The dissolution rate is assumedto be proportional to this stretching. The growth of a semi-infinite crack lying in an infinite strip subjected todifferent degrees of mixed-mode loading is studied
