Numerical Analysis of the Effect of Spot Superposition on Laser Peen Forming of Aluminum Alloy Sheet
Key Engineering Materials(2018)
Abstract
In order to study the effect of laser spot superposition on aluminum alloy sheet forming by laser peening, the finite element analysis method was introduced to simulating the forming of 7075 aluminum alloy with different spot superposition case. The results showed that the forming effect and stress distribution of the metal sheet was effected by the laser spot superposition modes. The forming effect of transverse spot superposition mode was better than the other three spot superposition modes.
