Centrifuge testing to verify scaling of offshore pipeline ploughs (2018)
Journal Article
Robinson, S., Brown, M., Matsui, H., Brennan, A., Augarde, C., Coombs, W., & Cortis, M. (2019). Centrifuge testing to verify scaling of offshore pipeline ploughs. International Journal of Physical Modelling in Geotechnics, 19(6), 305-317. https://doi.org/10.1680/jphmg.17.00075

Offshore pipeline ploughs have previously been modelled at 1g with small 1:50 scale models designed to derive the parameters required for prediction of ploughing in terms of tow force requirements and potential advance rates. This was scaled up to pr... Read More about Centrifuge testing to verify scaling of offshore pipeline ploughs.

Rammed earth (RE) is a venerable construction technique, gaining attention today owing to its environmental and sustainable qualities. A key obstacle to its wider adoption is a lack of strength characterisation methods to aid in design and conservati... Read More about Strength characterisation of soil-based construction materials.

The point collocation method with a local maximum entropy approach (2018)
Journal Article

Meshless methods have long been a topic of interest in computational modelling in solid mechanics and are broadly divided into weak and strong form-based approaches. The need for numerical integration in the former remains a challenge often met by us... Read More about The point collocation method with a local maximum entropy approach.

An adaptive cracking particle method providing explicit and accurate description of 3D crack surfaces (2018)
Journal Article

Cracks in 3D have arbitrary shapes and therefore present difficulties for numerical modelling. A novel adaptive cracking particle method with explicit and accurate description of 3D cracks is described in this paper. In this meshless method, crack su...
