RISInfluence of Tensile Strain on Smooth Muscle Cell Orientation in Rat Blood Vessels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Blood vessels are subject to tensile stress and associated strain which may influence the structure and organization of smooth muscle cells (SMCs) during physiological development and pathological ...
Relationship Between Hypertension, Hypertrophy, and Opening Angle of Zero-Stress State of Arteries Following Aortic Constriction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Examination of changes occurring in the zero-stress state of an organ provides a way to study cellular growth in the organ due to change of physical stresses. The zero-stress state of the ...
Elementary Mechanics of the Endothelium of Blood Vessels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The endothelium lining human arteries is a continuum of endothelial cells. The flowing blood imposes a shear stress on the endothelium. To compute the internal stress in the endothelium, we ...
Zero-Stress States of Arteries
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The no-load configuration of a living organ is, in general, not the zero-stress state. The difference can be revealed by cutting up an unloaded organ to such an extent that the stress becomes ...
Control of the Shape of a Thrombus-Neointima-Like Structure by Blood Shear Stress
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fluid mechanical factors are thought to influence vascular morphogenesis. Here we show how blood shear stress regulates the shape of a thrombus-neointima-like tissue on a polymer micro-cylinder ...
Online Estimation Algorithm for a Biaxial Ankle Kinematic Model With Configuration Dependent Joint Axes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The kinematics of the human ankle is commonly modeled as a biaxial hinge joint model. However, significant variations in axis orientations have been found between different individuals and also ...
Transient Residual Stresses in Thermal Barrier Coatings: Analytical and Numerical Results
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Thermal barrier coatings (TBCs) provide thermal insulation to high-temperature superalloys. Residual stresses develop in TBCs during cool-down from processing temperatures due to the thermal expansion ...
Analysis of Interfacial Cracks in a TBC/Superalloy System Under Thermomechanical Loading
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In thermal barrier coatings (TBC) residual stresses develop during cool down from processing temperature due to the thermal expansion mismatch between the different layers (substrate, bond coat, ...
Damage Accumulation Mechanisms in Thermal Barrier Coatings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Progressive damage evolution leading to spallation was investigated in Electron Beam—Plasma Vapor Deposition (EB-PVD) partially stabilized zirconia thermal barrier coating (TBC) applied to Nickel-based ...
Moving Load and Prestress Identification Using Wavelet-Based Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A novel moving force and prestress identification method based on finite element and wavelet-based method for bridge-vehicle system is developed. A two-axle vehicle model and simple-supported beam ...
