Elastic surface crack interaction and its engineering critical assessment within the framework of fitness-for-service standards

Gabriel de Castro Coêlho, Dr. Antonio Almeida Silva, Dr. Marco Antonio dos Santos

In real industrial conditions, it’s common to witness the interaction of multiple cracks such that their stress fields and crack driving forces are disturbed. For coplanar cracks, a greater hazard is expected because of the amplification…
