RISModeling of Saccular Aneurysm Growth in a Human Middle Cerebral Artery
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Saccular aneurysm growth in a human middle cerebral artery is modeled. The aneurysm growth model was presented in a companion paper by and (“ A Model for Saccular Cerebral Aneurysm Growth by ...
Three-Dimensional Modeling and Computational Analysis of the Human Cornea Considering Distributed Collagen Fibril Orientations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experimental tests on human corneas reveal distinguished reinforcing collagen lamellar structures that may be well described by a structural constitutive model considering distributed collagen fibril ...
Anisotropic Mechanical Properties of Tissue Components in Human Atherosclerotic Plaques
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Knowledge of the biomechanical properties of human atherosclerotic plaques is of essential importance for developing more insights in the pathophysiology of the cardiovascular system and for better ...
Influence of Medial Collagen Organization and Axial In Situ Stretch on Saccular Cerebral Aneurysm Growth
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A model for saccular cerebral aneurysm growth, proposed by and (2007, “A Model for Saccular Cerebral Aneurysm Growth in a Human Middle Cerebral Artery,” J. Theor. Biol., 247, pp. 775–787; 2008, ...
Changes in the Mechanical Environment of Stenotic Arteries During Interaction With Stents: Computational Assessment of Parametric Stent Designs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Clinical studies have identified factors such as the stent design and the deployment technique that are one cause for the success or failure of angioplasty treatments. In addition, the success ...
Passive Biaxial Mechanical Response of Aged Human Iliac Arteries
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Inflation and extension tests of arteries are essential for the understanding of arterial wall mechanics. Data for such tests of human arteries are rare. At autopsy we harvested 10 non-diseased ...
Comparison of a Multi-Layer Structural Model for Arterial Walls With a Fung-Type Model, and Issues of Material Stability
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The goals of this paper are (i) to re-examine the constitutive law for the description of the (passive) highly nonlinear and anisotropic response of healthy elastic arteries introduced recently ...
Mechanical Stresses in Abdominal Aortic Aneurysms: Influence of Diameter, Asymmetry, and Material Anisotropy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Biomechanical studies suggest that one determinant of abdominal aortic aneurysm (AAA) rupture is related to the stress in the wall. In this regard, a reliable and accurate stress analysis of ...
A Methodology to Analyze Changes in Lipid Core and Calcification Onto Fibrous Cap Vulnerability: The Human Atherosclerotic Carotid Bifurcation as an Illustratory Example
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A lipid core that occupies a high proportion of the plaque volume in addition to a thin fibrous cap is a predominant indicator of plaque vulnerability. Nowadays, noninvasive imaging modalities ...
A Three-dimensional Finite Element Model for Arterial Clamping
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Clamp induced injuries of the arterial wall may determine the outcome of surgical procedures. Thus, it is important to investigate the underlying mechanical effects. We present a three-dimensional ...
