Numerical analysis of high velocity, oblique impacts and residual tensile strength of carbon/epoxy laminates (2020)
Journal Article

This paper presents prediction of the high velocity, oblique impact response and quasi-static residual tensile strength of thin [45/90/−45/0]2s carbon/epoxy laminates using finite element (FE) models. A High-Fidelity Finite Element Method (Hi-FEM) wi... Read More about Numerical analysis of high velocity, oblique impacts and residual tensile strength of carbon/epoxy laminates.

Virtual characterization of nonlocal continuum damage model parameters using a high fidelity finite element model (2020)
Journal Article

A virtual finite element framework is presented to provide the transition from a high fidelity model to a more computationally efficient continuum model for simulating fibre-dominated damage behavior in composite laminates subjected to tensile loadin...

In situ characterization of trans-laminar fracture toughness using X-ray Computed Tomography (2020)
Journal Article

The change in the critical strain energy release rate as damage evolves, known as the R-curve, is of crucial importance to the understanding of fracture behaviour. The examination of damage evolution ahead of the crack tip in order to determine accur...

Novel tape termination method for automated fibre placement: Cutting characteristics and delamination suppression (2020)
Journal Article

A novel tape termination method for tapering the ply end and removing the fibre discontinuity owing to a dropped ply in a tapered composite was demonstrated. The forces required for this process – referred to as tape scarfing – were experimentally in...

An experimental study of scaling effects in notched quasi-isotropic carbon/epoxy laminates under compressive loads (2020)
Journal Article

The size effects in centre-notched quasi-isotropic carbon/epoxy laminates under compression were investigated. The in-plane dimensions of the baseline specimen were scaled up by a factor of up to 14. The centre-notched specimens were compared to open... Read More about An experimental study of scaling effects in notched quasi-isotropic carbon/epoxy laminates under compressive loads.

Effect of out-of-plane wrinkles in curved multi-directional carbon/epoxy laminates (2020)
Journal Article

Defects such as out-of-plane wrinkles are known to strongly affect in-plane strength but there has been very little research on their effect on out-of-plane properties. Experimental and numerical studies of multi-directional curved-beam laminates wer... Read More about Effect of out-of-plane wrinkles in curved multi-directional carbon/epoxy laminates.
