Career Summary

Biography

Dr. Mason Crumpton holds a bachelor degree in civil engineering with first class honors from The University of Newcastle and a Ph.D in civil engineering from the same institution. His Ph.D. research focused on the development of a highly efficient Adaptive Discontinuity Layout Optimisation (ADLO) computer program for solving geotechnical stability problems. The program employed novel mesh refinement techniques and optimisation algorithms to simulate the collapse of geostructures such as footings, tunnels, and slopes.

More recently, Dr. Crumpton has continued his career as a research associate with the Priority Research Centre for Geotechnical Science and Engineering (PRCGSE). In this role he has been working to develop powerful methods for modelling the effects of fracture propagation through rock using phase-field finite element technology. The aim of this work is to provide engineers with new tools for analysing the behavior of underground openings and rock slopes, though the potential applications are far reaching.

In addition to his research work, Crumpton maintains active engagement with the wider engineering community through his longstanding commitment to the Newcastle Chapter of the Australian Geomechanics Society. He held the position of Chapter chair and National representative from 2016 until 2018 and is currently an elected member of the local committee.

Discontinuity Layout Optimization (DLO) (Smith & Gilbert 2007) is an upper bound limit analysis technique for modeling the stability of geotechnical problems. Meshes used for DLO are typically generated by interconnecting a set of nodes (n) located at regular grid points within a domain. A regular grid allows the required mesh topology to be generated in approximately O(n 2) time by searching for pairs of integer coordinates with unity as their greatest common divisor. This technique avoids impractical O(n 3) worst case mesh generation times, but produces a non-optimal discretization. Using the concept of point-line duality, a procedure for assembling meshes on a non-uniform cloud of nodes in O(n2) time is proposed. The flexibility afforded by this newmethod is used to adaptively refine a DLO mesh by adding nodes in regions with the greatest estimated error. The effectiveness of this procedure is demonstrated by analyzing the stability of a strip footing on a Mohr-Coulomb soil. © 2015 Taylor & Francis Group, London.
