The dynamic response of component bolted joints often plays a significant role in the overall behavior of a structural system. Accurate finite element simulation of these problems requires proper treatment of the interface conditions. We present a formulation carefully suited to these problems that incorporates discontinuous Galerkin (DG) treatment locally at the interface. The present work is ...

• A calibrated, stress-state based SPR process FE model is developed. The joining feasibility and joint quality of a wide range riveted connections investigated. High rivet leg inner radius values are shown to increase the quality. Low central tip depths relate high probabilities successful formation. Machine learning techniques can classify for riveting scenarios. Developing robust numerical s...

Julian Gough studied protein structure analysis; then combined it with sequence comparison methods to produce a bioinformatics resource mapping all known structural domains to all completely sequenced genomes. This resource has provided the data for him, his colleagues and others in the field to understand the evolution of the protein repertoire. To compare and contrast structured and disordere...
