In this paper, we study two-dimensional thin-film flow inside a stationary circular cylinder driven by an imposed surface shear stress. Modelling is motivated by a need to understand the cooling and film dynamics provided by oil films in an aero-engi...

We investigate the quasi-static simple shear flow of a two-dimensional assembly of cohesionless particles using discrete element method (DEM) simulations. We focus on the unsteady flow regime where the solid would experience significant evolution of... Read More about Discrete element modelling of material non-coaxiality in simple shear flows.

Dies and moulds, which are essential tools for manufacturing engineered products, usually fail or become obsolete after a certain period of use for a variety of reasons. Thus, they often need remanufacture. The objectives of this paper are to review... Read More about A review on remanufacture of dies and moulds.

Predicting the coefficient of thermal expansion for textile composites based on a unit cell approach (2013)
Presentation / Conference Contribution
Brown, L. P., Zeng, X., Long, A. C., Brooks, R., & Jones, I. A. Predicting the coefficient of thermal expansion for textile composites based on a unit cell approach. Presented at Texcomp-11 Conference

The study focuses on unit cell FE modelling to predict coefficients of thermal expansion (CTEs) for sheared fabric laminates. Shear, as a dominant deformation mode in textile composites forming, introduces high degrees of anisotropy in both elasticit...

Presentation / Conference Contribution
Brown, L. P., Zeng, X., Long, A., & Jones, I. A. Recent developments in the realistic geometric modelling of textile structures using TexGen. Presented at 1st International Conference on Digital Technologies for the Textile Industries

Realistic geometric representation of fabrics is essential for modelling of mechanical and physical properties of textiles and textile composites. It is also advantageous to be able to generate those models quickly and easily. Recent developments in...
