On the validity of using idealised sample geometries for interpreting mechanical tests of very soft tissues
Sajjad Arzemanzadeh, Karol Miller, Adam Wittek
Mechanical characterisation of soft tissues often relies on inverse analysis of experimental data in which constitutive models are calibrated to match experimental force-displaceme…
Stacked Ensemble Learning for Abdominal Aortic Aneurysm Segmentation in CT Angiography
Joshua Fry, Sajjad Arzemanzadeh, Saeideh Sekhavat +9
Abdominal aortic aneurysm (AAA) rupture risk assessment increasingly relies on patient-specific biomechanical computations, which require accurate three-dimensional aneurysm geomet…
Mechanical behaviour of brain-skull interface (meninges) under shear loading through experiment and finite element modelling: Preliminary results
Sajjad Arzemanzadeh, Karol Miller, Tim Rosenow +2
The brain-skull interface (meninges) plays a critical role in governing brain motion during head impacts, yet computational models often simplify this interface using idealized con…
On the Appropriateness of Linear Stress Recovery in Biomechanical Analysis of Abdominal Aortic Aneurysm
Alastair Catlin, Mostafa Jamshidian, Adam Wittek +1
Abdominal aortic aneurysm (AAA) wall stress is a candidate rupture risk marker but is typically computed from single-phase images without known cardiac phase. Linear stress recover…
Impact of Geometric Uncertainty on the Computation of Abdominal Aortic Aneurysm Wall Strain
Saeideh Sekhavat, Mostafa Jamshidian, Adam Wittek +1
Abdominal aortic aneurysm (AAA) is a life-threatening condition characterized by permanent enlargement of the aorta, often detected incidentally during imaging for unrelated condit…
Towards personalised assessment of abdominal aortic aneurysm structural integrity
Mostafa Jamshidian, Adam Wittek, Saeideh Sekhavat +13
Abdominal aortic aneurysm (AAA) is a life-threatening condition characterized by the progressive dilation of the aorta, which can lead to rupture if undetected or untreated. Stress…
