The deformation produced after the machining of a structural component is known as part distortion. This phenomenon is a consequence of the inherent residual stresses that exist in raw materials. In this study, such phenomenon is numerically investigated in simple plate elements by considering their thicknesses and their corresponding contribution to part distortion. A total number of eleven flat plates were analyzed using a numerical part distortion procedure for finite element models that also considered their machining positions. The results of this study show that part distortion has more impact on slender plates because these present higher loads than thicker plates in which the residual stresses self-balance throughout their section. Consequently, the part distortion phenomena in simple structural flat plates are related the plate thickness, their machining position, and geometrical parameters.

结构件加工后产生的变形称为零件变形。这种现象是原材料中存在的固有残余应力的结果。在这项研究中，通过考虑它们的厚度和它们对零件变形的相应贡献，在简单的板单元中对这种现象进行了数值研究。使用有限元模型的数值零件变形程序分析了总共 11 个平板，同时考虑了它们的加工位置。这项研究的结果表明，零件变形对细长板的影响更大，因为细长板比在整个截面中残余应力自平衡的厚板承受更高的载荷。因此，简单结构平板中的零件变形现象与板厚有关，
