... to assess the effect of pulse energy level and operating temperature on residual stress induced on Ti-6Al-4V workpiece during nanosecond laser shock peening with 5 ns laser pulse width. The commercial FEM software package ABAQUS is employed to conduct FEM simulation of single shot laser peening of Ti-6Al-4V...

...STUDY OF EFFECT OF REPETITION RATE ON LASER SHOCK PEENING USING FINITE ELEMENT MODELING Sai Kosaraju, and Xin Zhao. Department of Mechanical Engineering, Clemson University, Clemson, SC, USA ABSTRACT A two-dimensional finite element model is developed to simulate the interaction between metal...

... Abstract In this paper, the surface microstructure evolution of an AZ31B magnesium (Mg) alloy during laser shock peening (LSP) was investigated. Particular attention was paid to the deformation twinning behavior, which plays an important role in the mechanical properties of Mg alloys...

... Abstract This study investigates the effects of laser shock peening (LSP) on residual stress, near surface modification, and hardness of Inconel 718 (IN718) specimens manufactured by selective laser melting (SLM) technique. Optical microscope and electron backscattered diffraction (EBSD...

... or processing. Laser shock peening (LSP) is an advanced laser-based surface processing method which has been utilized improve the surface hardness, fatigue performance, and corrosion resistance of Mg alloys. Recent studies show that LSP can bring significant texture weakening and grain refinement effect in Mg...

... strengths are ideal biocompatible metallic materials. The problem with Mg implants is how to control corrosion rates so that the degradation of Mg implants may match with bone growth. The high compressive residual stress induced by laser shock peening (LSP) has a great potential to slow down the corrosion...

... in comparison with laser shock peening (LSP). In this paper, the use of LSP along with an automatic X-Y table proves to be an attractive and reliable method for producing micro dent arrays with enhanced surface integrity and free of cracks. Surface topography, residual stress, and microhardness...
