Effects of residual stress on elastic-plastic fracture

Some current projectsMultiaxial creep stress relaxation in 316H steel

Above: Modelling of creep stress relaxation.Right: Measurement of creep-affected specimens.

Above: Synchrotron X-ray radiograph of a crack tip during ductile tearing of ferritic pressure vessel steel.Left: Neutron diffraction and digital image correlation measurement of a 7000-series aluminium alloy specimen during fracture.

Some current projectsPressurised thermal shock in reactor pressure vessels

Integrity of Wire + Arc Additive Manufactured structuresLeft: Stress profile in a WAAM specimenFar left: WAAM used to create a large metal structure

Right: Thermal shock in a simulated reactor pressure vessel.

Interaction of neighbouring defects in structuresRight: Interaction between a pair of co-planar semi-elliptical defects.
