From test data to FE code: a straightforward strategy for modelling the structural bonding interface

Show other versions (1)

A straightforward methodology for modelling the cohesive zone (CZM) of an adhesively bonded joint is developed, by using a commercial finite element code and experimental outcomes from standard fracture tests, without defining a damage law explicitly. The in-house developed algorithm implements a l...
