A combined XFEM and cohesive zone model for composite laminate microcracking and permeability
Grogan, DM,Bradaigh, CMO,Leen, SB; Grogan, David M.; Ó Brádaigh, Conchúr M. (Elsevier ScienceDirect, 2014-10-07)A novel computational methodology for predicting three-dimensional microcracking and permeability in composite laminates is presented, The methodology simulates microcrack initiation and propagation using the extended ... -

Grogan, David M.; Ó Brádaigh, Conchúr M.; McGarry, J. P.; Leen, Sean B. (2015-09-07) -
Damage characterisation of cryogenically cycled carbon fibre/PEEK laminates
Grogan, David M.; Leen, Sean B.; Ó Brádaigh, Conchúr M. (Elsevier ScienceDirect, 2014-08-14)A unique insight into damage formation in CF/PEEK laminates before, during and after cryogenic cycling, using optical microscopy and 3D X-ray computed tomography (CT), is presented. Thicker laminates were found to exhibit ... -
Design of composite tidal turbine blades
Grogan, David M.; Leen, Sean B.; Kennedy, Ciaran; Ó Brádaigh, Conchúr M. (2013-02-24)Tidal turbine blades are subjected to significant thrust and torsional loadings due to the high density ofthe seawater in which they operate. These thrust loadings lead to high bending moments at the bladeroot, which can ... -
Permeability of carbon fibre PEEK composites for cryogenic storage tanks of future space launchers
Flanagan, M.; Grogan, David M.; Goggins, Jamie; Appel, Simon; Doyle, K.; Leen, Sean B.; Ó Brádaigh, Conchúr M. (Elsevier, 2017-06-15)This work presents an experimental investigation into the permeability of carbon fibre (CF) polyetheretherketone (PEEK) for cryogenic storage tanks for space applications. The effects of cryogenic cycling, manufacturing ... -
An XFEM-Based Methodology for Fatigue Delamination and Permeability in Composites
Grogan, David M.; Leen, Sean B.; Ó Brádaigh, Conchúr M. (2014)Carbon fibre reinforced polymers (CFRP) are one of the prospective material families being investigated for use in the fuel tanks of future reusable space launch vehicles (RSLVs). The extreme thermo-mechanical loading that ...
