Abstract

Purpose: To analyze and estimate the strength of duralium rivets which had been treated
by using multistage artificial aging compared with duralium that had not been treated. This
processwas necessary to be conducted in riveting process effectively. Duralium has been
widely used in aerospace industry, one of duralium usage in aerospace industry is aircraft
fittings such as rivet. Riveting is one of method that used for joining airframe structural
components. During riveting process, the load transfer causing stress that led to the fatigue.
Riveting process also causes deformation on the rivet and sheet metal. Deformation that
occurs on the rivet will affect the performance of rivet structure. Thus, duralium rivet was
analyzed its total deformation, shear stress, and its equivalent stress Von Misses.
Design/methodology/approach: that used in this study was finite element analysis.
Geometry of rivet that used in this study was drawn by using Autodesk Inventor Professional
2018. While total deformation, shear stress and equivalent stress Von Mises on duralium
rivets were found out by using ANSYS Workbench 18.1.
Findings: Comparison result was obtained between duralium rivet with and without
treatment of multistage artificial aging. The result shown that total deformation, shear stress
and equivalent stress Von Mises which obtained by duralium rivet with multistage artificial
aging had the lower value than duralium rivet without multistage artificial aging. Duralium
rivet with multistage artificial aging could be used as aircraft fitting which had the higher
strength.
Research limitations/implications: Direct experiment on duralium rivet had not been
done yet, this study only did simulation based on data that obtained form previous research
that had been conducted by the researcher.
Practical implications: Duralium rivet with multistage artificial aging had lower value on
total deformation, shear stress, and equivalent stress Von Misses, thus duralium rivet with
multistage aritificial aging had a higher strength.
Originality/value: Application of duralium as a rivet with treatment of multistage artificial
aging.
