Shot peening is a major finishing treatment aiming to enhance parts’ life. However, the recourse to simulation to master the process and its effects still suffers from problems due to its complexity. The current paper presents a finite element-based approach that considers the random aspect of the shot peening process in association with a large number of shots, making it more realistic. The developed method is found to allow a computing time gain up to 70 % with comparable results to those obtained by the discrete element method, which has been reported as the most suitable for shot peening simulation. The comparison of both simulations results to experiment returned a good agreement. Simulations and experiences were concerned with C75 Almen-like strips.

喷丸处理是一种主要的后处理，旨在延长零件的使用寿命。然而，由于其复杂性，求助于仿真以掌握该过程及其效果仍然存在问题。当前的论文提出了一种基于有限元的方法，该方法考虑了喷丸处理的随机方面以及大量的喷丸，使其更加真实。发现开发的方法可以使计算时间增加多达70％，其结果与离散元素方法获得的结果相当，据报道，离散元素方法是最适合喷丸强化模拟的方法。两种模拟结果与实验的比较得出了很好的一致性。模拟和经验与C75 Almen型钢带有关。
