Experimental investigation of high velocity oblique impact and residual tensile strength of carbon/epoxy laminates (2019)
Journal Article
Composite components are required to be resilient against Foreign Object Damage (FOD) induced by localised high velocity impact events. Here an experimental investigation into high velocity oblique impacts and residual tensile strength of thin quasi-...

Deducing the R-curve for trans-laminar fracture from a virtual Over-height Compact Tension (OCT) test (2018)
Journal Article
The R-curve for Mode I trans-laminar fracture energy in quasi-isotropic IM7/8552 carbon/epoxy laminates is here deduced numerically from a virtual Over-height Compact Tension (OCT) test. A High-fidelity Finite Element Method (Hi-FEM) using the explic... Read More about Deducing the R-curve for trans-laminar fracture from a virtual Over-height Compact Tension (OCT) test.
Thickness effect on Mode I trans-laminar fracture toughness of quasi-isotropic carbon/epoxy laminates (2018)
Journal Article
The thickness dependency of trans-laminar fracture toughness was studied in centre-notched quasi-isotropic IM7/8552 carbon/epoxy laminates with central double 0° plies with thicknesses between 1 and 8 mm. A reduction in trans-laminar fracture toughne... Read More about Thickness effect on Mode I trans-laminar fracture toughness of quasi-isotropic carbon/epoxy laminates.
