Part Distortion Modeling on Aluminum Slender Structural Components for Aeronautical Industry

摘要

During the manufacturing of slender thin-walled aluminum components for the aeronautical industry, the appearance of part distortion once they are machined is a common problem, mainly due to the presence of residual stresses on the aluminum stocks. In this paper, the development of an agile analytical model for the calculation of the final distortions of machined components is proposed, accounting for different part geometries. The capability of the model to predict the final distortion in these pieces has been validated by comparing results of distortions of specimens obtained in experimental tests.
