Stress Gradient Effects on Notched Composite Failure Using a Local-Global Approach [PDF]
45th AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics & Materials Conference, 2004 Micromechanics based analysis to predict damage initiation in compressively loaded symmetric notched multidirectional laminates under remote uniaxial loading is described. A novel hybrid local-global finite element method in conjunction with the commercial code ABAQUS is used to solve the governing system of equations.

A Novel Estimation Approach of Pressure Gradient and Haemodynamic Stresses as Indicators of Pathological Aortic Flow Using Subvoxel Modelling [PDF]
IEEE Transactions on Biomedical Engineering, 2021 The flow downstream from aortic stenoses is characterised by the onset of shear-induced turbulence that leads to irreversible pressure losses. These extra losses represent an increased resistance that impacts cardiac efficiency. A novel approach is suggested in this study to accurately evaluate the pressure gradient profile along the aorta centreline ...
