Main theme: Effects of residual and thermal stresses on structural integrity.
Current research fellowship“Advanced Structural Analysis for the UK Nuclear Renaissance”
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.
