Strength of adhesively-bonded butt joints of tubes subjected to combined high-rate loads

The dynamic strength of adhesively-bonded joints was investigated experimen tally. The strength of the bonded joints under combined high rate loading w as measured using the clamped Hopkinson bar method. Tubular butt joints bon ded by epoxy resin were used For the experiment. Combined stress waves of t ension and torsion were applied to the specimens. The strength of the adhes ively-bonded joint was determined by measuring the stress waves propagated in the load output tube of the specimen. It was found that the dynamic stre ngth of the adhesive joints was greater than the static strength under tens ile and shear load.
