Biography

Piaras completed a BSc in Mathematical Physics at University College, Dublin (1987), majoring in numerical analysis. He obtained a PhD (DPhil) from the Department of Engineering Science at the University of Oxford (1993), carrying out a theoretical study of the strength of components made of bonded dissimilar materials.

In 1995, he joined the Oxford Orthopaedic Engineering Centre at the Nuffield Orthopaedic Hospital, UK, to study failure of knee prostheses and damage to human articular cartilage. During this period, he co-authored the book “Solution to Crack Problems” which was based on techniques developed in the preceding years. He re-joined the Solid Mechanics group at Oxford as a Research Fellow, carrying out work on the development of plasticity around propagating cracks.

Piaras joined the Department of Engineering Science at The University of Auckland as a lecturer in 1999. Since then, amongst other things, he has worked on the constitutive modelling of fibrous materials and the mathematical modelling of composite materials manufacturing processes. He has over 80 publications in the fields of Composite Materials, Textile Mechanics, Biomechanics, Geomechanics and Fracture Mechanics.
