Detailed finite element investigation of cross weld specimens highlights the key role of plastic strain localisation in the heat affected zone of a welded connection.

Identification and calibration of cyclic plasticity material constants for parent, weld and heat affected zone regions using a non-linear kinematic–isotropic hardening material model.

Application of a multi-material cyclic plasticity model to a T-joint welded connection. The predicted critical location corresponds to the location of failure observed in-service.
