It is demonstrated experimentally that the laser heating process can be employed for fatigue crack growth retardation in aircraft aluminium structures. A numerical methodology for the quantitative prediction of the resulting fatigue crack growth in laser heated specimens is developed and validated on basis of the experimental results. Then the validated methodology is employed for numerically based design optimization.
