Аннотация
An investigation concerning the influence of laser shock processing (LSP) of stainless steel specimens made of 03Kh22N6M2 steel for the fatigue life by finite element modeling was performed. The known experimental fatigue life parameters were compared with the data taken from the finite element modeling. A conforming comparison is observed between the numerical and experimental data. It was shown that the thickness of the specimen is an important parameter during application of the LSP technology. It was found that with the decrease in the specimen thickness the fatigue life, conditioned by the LSP application, improves significantly. It was shown that for thin specimens (about 2 mm) the application of the LSP technology improves the fatigue life to 300%.
