研究目的
Investigation of the specimen thickness for the fatigue behavior of specimens made of the 03Kh22N6М2 stainless steel subjected to the LSP technology.
研究成果
The influence of the specimen thickness made of the 03Kh22N6М2 stainless steel subjected to laser-shock-wave processing (LSP) was investigated. It was shown that after application of LSP for thin specimens (2-mm thickness) the fatigue life increased by more than 300%. The regularity showing that the thinner the specimen the higher the LSP effect for increasing the fatigue resource was proved. The algorithm of the finite element modeling is a powerful instrument in the process of determination and optimization of the impact parameters during application of the LSP technology to certain components of the machine, especially to the thin-wall structures at the stages of designing and manufacturing.
研究不足
The computational cost during modeling, with account of all processes observed during LSP, will be huge and it will be incomprehensible for ordinary computers (supercomputers will be required).
