“…Moreover, for the real particle impact process, not single or several particles but massive amounts of particles are simultaneously impacting on the target. According to this view, Arani et al [10] developed the SPH-FEM method and successfully simulated the material removal behaviors of the impact target. On the other hand, Liu and Wan [11] conducted FEM simulations by using the Johnson-Cook constitutive model and shear failure model to explore the effects of particle shapes on the erosion mechanism.…”

In this study, experimental and numerical investigations have been done to explore the effect of the particle properties on the erosion behavior of aluminum alloy during the abrasive air jet machining process by using the novel medium-hard amino thermoset plastic (ATP) and conventional super-hard alumina (Al 2 O 3 ) particles. In the numerical simulation, a novel linear elastic material model with the failure standard was proposed to de ne the ATP particle and the conventional rigid material model was used to de ne the Al 2 O 3 particle; and the impact target model was established by using smooth particle hydrodynamics (SPH) interpolant with the moving-least-squares method. Then a multi-particle impact model based on the SPH and nite element coupling method (SPH-FEM) was developed to investigate the particle impact process. It indicates that the SPH-FEM method can be used to simulate the erosion behaviors of aluminum alloy impacted by the medium-hard ATP particle, and the simulation results are fundamentally consistent with the experimental ones. The results demonstrate that the effect of particle hardness on the erosion behavior of the impact target is about 200 times higher than that of compressive air pressure. More signi cantly, there exists an optimal impact angle where the surface material can be removed by chip formation resulting in the maximum material removal rate and the surface erosion behavior can be accurately predicted by simulation. Furthermore, with the particle hardness increasing, such optimal impact angle would be reduced accordingly.

“…SPE is the progressive removal of material from the surfaces of the target material due to repeated impacts of erodent particles. It has been reported that SPE causes damage in various engineering applications such as turbine blades of power plants, aircraft, pipelines, several parts in the oil and rig industry, and motor vehicles [1,2]. Components exposed to SPE either lose their functionality or their lifetime is substantially decreased.…”

“…Results showed enhancement in impact damage resistance of solar panels due to the applied tempering process. There are some modeling efforts of SPE in the literature, too [1,[33][34][35][36][37][38]. Several other studies on the particle erosion behavior of different materials are available in the literature [39][40][41][42][43][44].…”

The solid particle erosion (SPE) performance of three different transparent materials, polycarbonate solid sheet, plexiglass (Polymethylmethacrylate (PMMA), and laminated glass was investigated. Erosion tests were performed under different impact angles (20°, 30°, 45°, 60°, and 90°) and impinging velocities (75, 150, and 200 m/s). As erodent particles, alumina (Al2O3) with 52 µm average diameter and silicon carbide (SiC), particles with two different dimensions (71, and 348 µm in diameters) were used. The results showed that polycarbonate specimens outperformed the other tested samples regardless of impact velocity and impinging angle conditions. When the erosion resistance of samples at 90° and 75 m/s is taken into consideration, the polycarbonate sheet was found to be at least 14 times more erosion resistant compared to plexiglass, and 23 times more resistant than the laminated glass materials. In addition, polycarbonate exhibited an incubation behavior at lower impact velocity, and with SiC erodent.

An smooth particle hydrodynamics/finite element (SPH/FEM) model was developed to simulate the erosion of zirconia particle‐reinforced epoxy composites, due to the overlapping impacts of angular particles at both perpendicular and oblique incidences. For each composite target, multiple sub‐volumes, each having their own random reinforcement distribution, were modeled. The reinforcements were assumed as noneroding and nondeforming and were distributed in the modeled sub‐volumes according to the random distributions measured in the actual samples. Erosion tests were performed to verify the numerical model, and it was found that the erosion rates of the zirconia‐reinforced composites were in all cases significantly lower than the neat epoxy. The experimentally‐observed erosion mechanisms were successfully simulated by the model, and the predicted erosion rates matched the measured ones to within 2% to 11%. It is anticipated that similar models can be used to predict erosion of other particulate composite systems whose reinforcement erosion and fracture is negligible compared to the matrix erosion.
