We　applied　the　fracture　mechanics　approach　and　the　non-linear　finite　element　method　to　the　analysis　of　interfacial　failure　in　the　cylindrical　rubber　bushes　bonded　on　their　outer　and　inner　curved　surfaces　to　rigid　metal　cylinders.　The　fracture　parameter,　tearing　energy　for　rubber　bushes　was　calculated　using　global　energy　change.　The　contact　of　interfacial　crack　during　deformation　was　considered.　There　exist　some　different　results　from　the　previous　linear　solutions.　©　2007.
