Journal Article
Damghani, M., Wallis, C., Bakunowicz, J., & Murphy, A. (2021). Using laminate hybridisation (CFRP-GFRP) and shaped CFRP plies to increase plate post-buckling strain to failure under shear loading. Thin-Walled Structures, 162, Article 107543. https://doi.org/10.1016/j.tws.2021.107543

Previous works have established the response and failure behaviour of hybrid (CFRP-GFRP) laminates when subjected to a wide range of destabilising loads. However, to date no works have quantified the influence of selective laminate shapes and hybridi...

Understanding the influence of laminate stacking sequence on strain/stress concentrations in thin laminates at repair holes with large scarf angles (2019)
Journal Article
Damghani, M., Bakunowicz, J., & Murphy, A. (2019). Understanding the influence of laminate stacking sequence on strain/stress concentrations in thin laminates at repair holes with large scarf angles. Journal of Composite Materials, 53(28-30), 4273-4284. https://doi.org/10.1177/0021998319855772

Scarf repair is widely used in the restoration of structural performance of damaged aircraft secondary structures. Such repairs result in reduced thickness sections which are significantly larger than those associated with typical fastener holes. Sig...
