Overview

Experimental and numerical investigation reveals strain-rate impact on bolted joint strength, suggesting design improvements for durability.

Key Points

  • This study aims to investigate the dynamic tensile failure mechanisms in composite/metal bolted joints under varying strain rates.
  • Conducted split Hopkinson tension bar tests with high-speed imaging on single-bolt CFRP/7075 aluminum joints.
  • Developed a three-dimensional Abaqus/Explicit model using the Hashin failure criterion to simulate damage progression.
  • Peak stress increased from 438.18 MPa at 1000 s −1 to 579.29 MPa at 3000 s −1.
  • Model predictions of peak stress aligned closely with experimental results, showing only a 4.08% error.
  • Damage initiation around the bolt hole intensified with increased strain rates, correlated with local failure mechanisms.
