Laser Peening Analysis of Aluminum 5083: A Finite Element Study
نویسندگان
چکیده
In this research, a finite element (FE) technique was used to predict the residual stresses in laser-peened aluminum 5083 at different power densities. A dynamic pressure profile create wave an explicit model, and stress results were extracted once solution stabilized. It is shown that as density increases from 0.5 4 GW/cm2, induced develop monotonically deeper 0.42 1.40 mm. However, with increase density, maximum magnitude of sub-surface only up certain threshold (1 GW/cm2 for 5083). Above threshold, complex interaction elastic plastic waves occurring peak pressures above ≈2.5 Hugoniot Elastic Limit (HEL) decreased surface stresses. The FE are corroborated physical experiments observations.

Effects of simulation parameters on residual stresses for laser shock peening finite element analysis
By using finite element analysis, we proposed an applicable finite element method of laser shock peening (LSP) and discussed various parameters, such as solution time, stability limit, dynamic yield stress, peak pressure, pressure pulse duration, laser spot size, and multiple LSP. The effects of parameters related to the finite element simulation of the LSP process on the residual stresses of 3...
متن کاملStudy of anisotropic character induced by microscale laser shock peening on a single crystal aluminum
The beam spot size used in microscale laser shock peening is of the same order as grain size in many materials. Therefore, the deformation is induced in only a few grains so that it is necessary to treat the material as being anisotropic and heterogeneous. In order to investigate the corresponding anisotropic features, different experimental techniques and three-dimensional finite element simul...
