A numerical simulation to relate the shot peening parameters to the induced residual stresses

Finite element modelling of shot peening process- A progress overview

“…It is worth noting that although above works [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38] provide a powerful method for establishing quantitative relationships between shot and target parameters and residual stress characteristics, FE methods could not still simulate a stream of discrete shots impacting on a target. Recently, discrete element (DE) method has been adopted to simulate shot peening process by Han et al [39][40][41].…”

“…With the appearances of powerful finite element software such as ABAQUS, ANSYS and NASTRAN, attention was focused on numerical simulation of shot peening process [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38]. Such a simulation method provides a cheap and easy way to study the dynamic impact of a shot with high velocity, the double non-linearity of the problem due to the contact of two bodies and the elastic-plastic behaviour of the target, etc.…”

Nondestructive residual strain measurement using high energy x-ray diffraction

“…This approach needs either a functional or numerical model for the strain depth profile of shot peened material. There are already some simple functional and more complicated numerical forms that describe strain depth profiles (56)(57)(58)(59)(60)(61)(62)(63)(64)(65)(66)(67)(68)(69). The problem with the functional forms is that they do not seem to be accurate enough to explain the intensity depth profiles we are getting from shot peened aluminum.…”

Parametric study on single shot peening by dimensional analysis method incorporated with finite element method

“…(4), when the dimensionless parameters are unchanged, the maximum compressive residual stress σ m depend only on the impact energy density; and the maximum depth of dent h m is proportional to the radius of the shot, whereas σ m is independent of it, which is consistent with the conclusions obtained from Refs. [14,17,18,20,21,25].…”

“…In recent years, many analytical and numerical models, with which the residual stress, the surface integrity and the influence of parameters can be predicted, have been applied to analyze the SP process to take advantage of advancements in computer technology [5,6,[8][9][10][11][12][13][14][15]. The effects of some SP parameters have been investigated [2,[16][17][18][19][20][21], however, little research has focused on systematic analysis of dimensionless parameters in SP process, which is important for clarifying the influence of process conditions. Kelmenz et al [14] studied the residual stress state after shot peening with dimensional analysis method and finite element method (FEM) simulation, and the effects of four dimensionless input values were investigated.…”
