Fastener stiffness measurement methodology

Popis výsledku v původním jazyce

The stiffness of fasteners is needed for calculation of crack growth and damage tolerance parameters for large aeronautical structures. Experiments were performed on single fastener specimens made of aluminium alloy joined by aluminium rivets. The joints were loaded in pairs to prevent secondary bending and the load was introduced by increasing steps to monitor the change in stiffness with the increasing load level. Various plate thicknesses from 1.2 mm up to 6 mm and different rivet diameter combinations were analysed based on the structure of L-410 NG airplane. The paper includes the results of quasi-static testing of the riveted joints and a comparison with analytical models. The modelled stiffness was on average 16% higher than measured values. Maximum analysed difference was 44% which means that the experiment is irreplaceable.
