Influence of interference-fit size on bearing fatigue response of single-lap carbon fiber reinforced polymer/Ti alloy bolted joints

Fretting accelerates damage of mechanical joint; however, the interference-fit technology which makes an oversized fastener installed into a hole has been a method for durability enhancement. An experimental investigation was conducted to determine the effect of interference-fit size on the fretting fatigue life, hole elongation, and circumferential strain of carbon fiber-reinforced polymer(CFRP)/Ti alloy bolted joints. The relationship between...
