“…The coupling of FE analysis for modeling the subsurface behavior with SPH (Smooth Particles Hydrodynamics) or DEM (Discrete Element Methods) allows to consider the description of the flow of shots and its interaction with any surface. Murugaratnam et al (2015), Tu et al (2017) and Zhang et al (2018) relied on analogous DEM-FEM approaches to model coverage, roughness and residual stresses profiles. The positions and initial velocities of shots are output from a DEM software and applied as initial condition in a FE analysis.…”

“…For numerically evaluating Almen intensity, Almen arc height h was related to residual stress profile through equation 5by Guagliano 39 and related to impact number N by Miao et al 44 using equation (6). These two equations were derived through fitting simulation results derived by other researchers such as Miao 89 and Tu et al 106 Other equations to predict arc height of intensity through either coverage or number were derived by Kim et al 79 based on an area-averaged solution. Encouragingly, results predicted by the two equations corresponded well with the experimental results obtained from Kim et al 24,34 The latest progress in this aspect is the prediction function for Almen height which was derived through the regression method.…”

“…Current computer resources required to use Finite Element Method (FEM) alone for realistic shot-peening investigations are still not feasible. This paved the way for the use of the discrete element method (DEM) more recently, either alone or coupled with FEM concurrently by Han et al [25], Jebahi et al [26], or sequentially by Murgaratnam et al [27], Bhuvaraghan et al [28], and Fubin-Tu et al [29], to overcome the challenges associated with the FEM method.…”

“…The work is patterned after the work of Bhuvaraghan et al [28], where the pressure equivalent of the force was applied to the component using a fixed dent size of a single normal impact as the area of contact via an approximated mesh size. That approach, however, has considerable limitations with respect to a realistic SP process, as highlighted by Fubin-Tu et al [29], as well as with respect to its accuracy, since dents formation in a realistic SP cannot be uniform. The radius of the dent formed depends on the angle of impact, which is seldom normal to the workpiece surface, more so considering the shot-shot collision effects, which reduce the likelihood of a normal impact.…”
