%0 doctoral thesis,HZG report %@ 2191-7833 %A Schnubel, D. %D 2012 %J %N %P %T Laser heating as approach to retard fatigue crack growth in aircraft aluminium structures (Dissertation) %U %X 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.
