Investigating the effect of displacement rate on deformation and failure mechanisms in bonded elastomers

  • Chi T. Liu
  • Fu-Pen Chiang


Deformation and failure mechanisms in bi-material specimens were investigated under three different loading speeds (0.0254 cm/min, 0.254 cm/min and 2.54 cm/min). Two different viscoelastic materials were used to generate bi-material specimens. The experimental data were analyzed and the effect of applied displacement rate on strain distributions and interfacial failure mechanisms in the bonded specimens are discussed. Close inspection of the specimens showed that at failure initiation widely different deformation rates occurred at roughly the same global strain levels and were concentrated in the interphase regions near the bondlines.
