TL;DR: In this paper, a multidroplet impact model was proposed for predicting residual stresses induced on materials subjected to water jet peening, which considers the impact pressure distribution due to high-velocity droplets impinging on the material surface instead of stationary pressure distribution for prediction of residual stresses on water jet-peened surfaces.

Abstract: In this article, a multidroplet impact model, proposed for predicting residual stresses induced on materials subjected to water jet peening, is presented. This approach considers the impact pressure distribution due to high-velocity droplets impinging on the material surface instead of stationary pressure distribution for prediction of residual stresses on water jet-peened surfaces. It makes use of Reichardt's theory for predicting the velocity distribution of droplets and liquid impact theory for predicting the impact pressure and duration of impact of high-velocity droplets. For predicting residual stresses on the surface and subsurface of material subjected to water jet peening, finite element modeling approach was adopted by using transient elastoplastic finite element analysis by considering an impingement of a set of droplets in succession to one another over a certain time period after which this pressure is released. The effectiveness of the proposed approach was demonstrated bv comparing the pred...

High‐Speed Impact between a Liquid Drop and a Solid Surface

[...]

01 Dec 1969-Journal of Applied Physics

TL;DR: In this paper, the authors presented a two-dimensional approximation of the maximum impact pressure between a compressible liquid drop and a solid surface, which is valid only for the initial phase of the impact, during which the expanding shock front generated by the impact still remains attached to the target surface and no lateral outflow takes place.

Abstract: The dynamics of high‐speed impact between a compressible liquid drop and a solid surface are reviewed. Previous estimates for the maximum impact pressure have been based on one‐dimensional approximations. This paper presents a two‐dimensional approximation, adapted from a closely related analysis of the oblique impact between two solid plates. This is valid only for the ``initial'' phase of the impact during which the expanding shock front generated by the impact still remains attached to the target surface, and no lateral outflow takes place. The derivations assume a linear relationship between shock velocity and particle velocity change across the shock front. Numerical results are presented for water and sodium, and can be generalized as follows: The contact pressure remains substantially equal to the one‐dimensional pressure until the contact angle φ at the edge has reached about half of its critical value, at which the assumed model beaks down and lateral outflow must initiate. As this critical condition is further approached, the contact edge pressure increases progressively, and its critical value Pc is taken as the maximum impact pressure. The ratio Pc/ρ0C0V0 always exceeds about 2.75 exhibiting a minimum in the vicinity of V0/C0=0.2, where ρ0 and C0 are the density and acoustic velocity of the liquid, and V0 is the impact velocity. These pressures are considerably higher than have been heretofore supposed, but circumstantial experimental evidence supports the present results.

Abstract: A traversing water jet was used to impact the surface of 1100 series aluminum specimens in an effort to generate compressive residual stresses on the surface. Stresses induced by the water peening operation were measured using X-ray diffraction, and compressive stress increases as large as 60 percent of the monotonic yield strength resulted. Surface roughness and hardness were also measured. Finite element modeling of a stationary water jet impinging on an elastic-plastic half-space was performed to characterize the water peening process. Surface residual stresses were found to be a result of sub-surface plastic deformations.
