Effect of the clearance and interference-fit on failure of the pin-loaded composites

摘要

The aim of this study is to examine the effect of the clearance and interference-fit on the failure mode, failure load and bearing strength of the pin-loaded joints subjected to traction forces. The failure load and failure mode are determined both experimentally and numerically. Three-dimensional finite element models are created using ANSYS software. Non-linear contact analyses are performed to examine the effects of the clearance and interference for different ratios of the edge distance-to-hole diameter (E/D) and plate width-to-hole diameter (W/D). Damage is also examined using scanning electron microscope (SEM). It is observed that interference for all pin-loaded joint configurations is beneficial. A good agreement between experimental and numerical results is obtained.
