Simulation of multiple laser shock peening of a 35CD4 steel alloy

Impact toughness of a gradient hardened layer of Cr5Mo1V steel treated by laser shock peening

“…(1). Using finite element analysis to simulate the LSP process of 35CD4 steel alloy, Ding and Ye [28] reported that the surface compressive residual stress is almost unchanged while the plastically affected depth increases from 0.74 to 1.4 mm when the numbers of laser shots increases from one to three. Surface compressive residual stress plays an important role on the magnitude of surface impact toughness through restraining the generation and growth of crack.…”

Numerical simulation of residual stresses fields of DD6 blade during laser shock processing

“…LSP is well suited for precisely controlled treatment of localized fatigue critical areas, such as, holes, notches, fillets, and welds. It has been proposed as a competitive alternative technology to classical treatments for improving fatigue, corrosion, and wears resistance of metals [6,7].…”

Effects of laser shock processing with different parameters and ways on residual stresses fields of a TC4 alloy blade

“…Amarchintal et al [5] and Wu et al [6] discussed the dynamic characteristics of aluminum alloy and stainless steel during LSP process by simulation and experiment. Ding et al [7] and Hu et al [8] established dynamic responses model by ABAQUS and ANSYS/LS-DYNA during LSP, and a 35CD4 steel alloy and 1045 steel during LSP were computed numerically on residual stresses fields. Zhang et al [9] and Fang et al [10] in detail analyzed the effects of LSP on the residual stresses and stress corrosion of some common materials by experiments.…”
