چکیده مقاله:
The purpose of this paper is to evaluate the equivalent plastic strain (PEEQ) for riveted joints of Al-alloy ۲۰۲۴ plates. For this purpose, according to field observations, the parameters affecting the equivalent plastic strain are obtained. The relevant geometrical parameters such as rivets length, holes diameter, and dimensional tolerances as well as the rivet pattern and the rivet joints material are considered. In this study, modeling is performed using the finite element method. For this purpose, a three-dimensional elastoplastic model is used for simulation. The information obtained from the finite element method in this study made it possible to place the rivets in this type of joint for use in high-safety structures such as the aerospace industry. This method increases the confidence of the design of riveted joints and also reduces the cost and number of experimental tests related to determining the maximum equivalent plastic strain in this joint. Also, using this method reduces the costs of failure and fracture of sensitive components. The results showed that the geometric parameters and the rivet material have a significant effect on the equivalent plastic strain in riveted joints of Al-alloy ۲۰۲۴ plates.
