Finite element modelling of laser peening and laser peen forming of materials

ICALEO 2004: 23rd International Congress on Laser Materials Processing and Laser Microfabrication, 2004
The finite element simulation of LSP induced surface modifications (residual stresses and deformations, bending effect on thin targets), is of primary importance to predict accurate LSP conditions for a given application. We have carried out such simulations with the use of RADIOSS TM and ABAQUS TM commercial softwares, mainly on Ti6Al4V titanium ...

Laser peening and shot peening for titanium alloy blade

PICALO 2008: 3rd Pacific International Conference on Laser Materials Processing, Micro, Nano and Ultrafast Fabrication, 2008
The characteristic of laser peening (LP) and shot peening (SP) was introduced in this paper, then LP and SP for titanium alloy was studied respectively, including the surface profile and residual stress and fatigue properties. The results show that there was shocked zone with the laser spot size and 10~20 µm depth on the surface of the titanium alloy ...

Automated overlays for laser peening

International Journal of Structural Integrity, 2011
PurposeSacrificial opaque overlays used in laser peening provide optimal processing and protect the surface of the part being processed from thermal damage from the laser pulses. Traditional solid film overlays for laser peening often require several applications and the running of multiple partial laser peening sequences in order to completely process
