Effect of Metallic Inserts on the Strength of Pin Joints Prepared from Glass Fiber Reinforced Composites

Abstract

The present study deals with the failure analysis of pin joints by varying different geometric parameters i.e., edge distance to hole diameter (E/D) ratio and width to hole diameter (W/D) ratio. Pin joints were prepared from the glass fiber reinforced laminates incorporating the metal inserts. A range of 2 to 5 and 3 to 6 was considered for E/D and W/D ratios, respectively. The stress around the hole was redistributed by incorporating the metal inserts in the hole to increase the load carrying capacity. To predict the failure loads and failure modes numerically, progressive damage analysis along with Hashin failure criteria was used in the pin joints. Strength of the pin joints increased in the range of 65 per cent to 92 per cent with metal insert due to the redistribution of the stresses around the hole. Progressive damage analysis gave a good correlation with experimental findings. Thereafter, the strength of the joint was predicted by varying the thickness of the metal inserts.

Metal inserts for performance improvement in glass fiber‐reinforced polymer nanocomposite joints under accelerated aging conditions

“…The addition of metal inserts distributed the stress‐reduction around the hole boundary and enhanced the failure load. Singh et al [ 40 ] used metal inserts in pin joints to increase the strength in the range of 65%–95% for epoxy/glass‐fiber composites by distributing stress concentration around the hole. Giannopoulos et al [ 41 ] studied the effect of bolt preloads on the strength and fatigue behavior of the epoxy/glass‐fiber composite bolted joints.…”
