Recent progress, challenges and outlook for multidisciplinary structural optimization of aircraft and aerial vehicles (2022)
Journal Article

Designing an airframe is a complex process as it requires knowledge from multiple disciplines such as aerodynamics, structural mechanics, manufacturing, flight dynamics, which individually lead to very different optimal designs. Furthermore, the grow... Read More about Recent progress, challenges and outlook for multidisciplinary structural optimization of aircraft and aerial vehicles.

Weft Yarn Interlacement Modelling for 3D Profiled Structures (2021)
Journal Article

Currently, generation of 3D woven T-joint models with complex weave geometries, using TexGen software, is a manual process. One of the main challenges to automatic generation of these textiles is the order in which the weft yarns interlace within the...

An Abaqus plugin for efficient damage initiation hotspot identification in large-scale composite structures with repeated features (2021)
Journal Article

© 2021 Elsevier Ltd Identifying the hotspots for damage initiation in large-scale composite structure designs presents a significant challenge due to the high modelling cost. For most industrial applications, the finite element (FE) models are often...

Efficient meshing technique for textile composites unit cells of arbitrary complexity (2020)
Journal Article

Meso-scale unit cell models are often used to simulate mechanical behaviour of textile composites. Apart from reliable ways to create meso-scale geometries, such simulations require reliable meshing algorithms. While the former is made possible via d...

Development of methods for optimisation of complex 3D weave geometries (2018)
Journal Article

The development of 3D weaves has resulted in the ability to produce near net shaped preforms, with the additional advantage over unidirectional lay-ups and 2D weaves of greater delamination resistance provided by through-thickness reinforcement. 3D w...

Multi-scale wave propagation modelling for two-dimensional periodic textile composites (2018)
Journal Article

In this article, a method allowing vibro-acoustic and ultrasonic wave propagation analysis of highly anisotropic textile composites at a mesoscopic level is presented for the first time. The method combines the advantages of mode-based Component Mode... Read More about Multi-scale wave propagation modelling for two-dimensional periodic textile composites.

Geometric modeling of 3D woven preforms in composite T-joints (2017)
Journal Article

A common method to fabricate net-shaped three-dimensional (3D) woven preforms for composite T-joints is to weave flat 3D preforms via a standard weaving machine with variation in binder yarn path and then separate the preform in the form of a bifurca...

Effects of layer shift and yarn path variability on mechanical properties of a twill weave composite (2016)
Journal Article

Experimental and numerical analysis of a woven composite were performed in order to assess the effect of yarn path and layer shift variability on properties of the composite. Analysis of the geometry of a 12K carbon fibre 2×2 twill weave at the meso-... Read More about Effects of layer shift and yarn path variability on mechanical properties of a twill weave composite.

Analytical method using gamma functions for determining areas of power elliptical shapes for use in geometrical textile models (2015)
Journal Article

Textile models are often assumed to have homogenous and well defined cross-sections. For these models, the use of a power elliptical cross-sectional shape has been found to be beneficial as different shapes can be created, e.g. lenticular, elliptical...

Quantification of mesoscale variability and geometrical reconstruction of a textile (2015)
Journal Article

Automated image analysis of textile surfaces allowed determination and quantification of intrinsic yarn path variabilities in a 2/2 twill weave during the lay-up process. The yarn paths were described in terms of waves and it was found that the frequ... Read More about Quantification of mesoscale variability and geometrical reconstruction of a textile.

Stochastic reconstruction of filament paths in fibre bundles based on two-dimensional input data (2015)
Journal Article

Conventional optical microscopy is an inexpensive technique to analyse fibre bundle micro-structures. Compared to micro-computed tomography, the resolution is higher and larger samples sizes can be analysed. This provides, for example, detailed infor...
