Process modeling of laser peening to improve its performance in industry application

The Crystal Plasticity modeling method was introduced recently to predict the mechanical properties of AA2195-T6 Friction Stir Welded Joints after laser peening including compressive residual stresses, work hardening, and crystal morphology evolutions. Experimental and theoretical approaches are combined to quantify strengthening contributions of laser-peening-induced near-surface local plastic deformation effects on the enhancement of local and overall mechanical properties of AA2195-T6 friction stir welded joints. Furthermore, eigen-moment, derived from eigenstrain, is proposed to describe the bending behavior of metal plates in laser peen forming. To achieve process planning of laser peen forming, the distributed eigen-moment on two surfaces of the plates is prescribed, and a PDE-constrained optimization is utilized to describe the process planning problem for complex shaping. Several applications about laser peening of large-scale components will be introduced to show the model capabilities at last.

Novel Applications of Laser Shock Peening

For many aerospace structures, life enhancement involves the retardation of a long, growing, crack that may be many millimetres in length; and that in consequence is already generating high levels of stress intensity factor at the crack tip. As peening of the entire structure is neither feasible nor desirable, the possibility of using localised peen patches as crack retarding features is being actively explored. Recent work on the effectiveness of peen patches in aerospace aluminium for crack retardation, as well as methods for optimum peening of assemblies during manufacturing.

Thermal Mechanical Fatigue Testing of Laser Peened Die Cast Dies

Components made with the die casting process for a variety of products from computer, household, to transportation components. Because of the thermal cycling of these dies, they suffer from thermal mechanical fatigue. Extending the life of these dies decreases cost and system down time. Various techniques are used to extend die life and laser peening is a surface process providing significant increases in die life.
