RISCyclic Pressure and Angiotensin II Influence the Biomechanical Properties of Aortic Valves
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Hypertension is a known risk factor for aortic stenosis. The elevated blood pressure increases the transvalvular load and can elicit inflammation and extracellular matrix (ECM) remodeling. Elevated cyclic pressure and the ...
A Study on Onset of Liquid Entrainment in Low Pressure Depressurization System of Advanced Passive Pressurized Water Reactors
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: The low-pressure depressurization system (LPDS) of advanced passive pressurized water reactors (PWRs) is designed to provide depressurization of the reactor coolant system during a small break loss-of-coolant accident ...
Machine Learning Metamodel of a Computationally Intense LOCA Code
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The nuclear power industry is increasingly identifying applications of machine learning to reduce design, engineering, manufacturing, and operational costs. In some cases, applications have been deployed and are providing ...
Anisotropic Compressive Properties of Passive Porcine Muscle Tissue
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The body has approximately 434 muscles, which makes up 40–50% of the body by weight. Muscle is hierarchical in nature and organized in progressively larger units encased in connective tissue. Like many soft tissues, ...
Quantitative Analysis of Tissue Damage Evolution in Porcine Liver With Interrupted Mechanical Testing Under Tension, Compression, and Shear
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, the damage evolution of liver tissue was quantified at the microstructural level under tensile, compression, and shear loading conditions using an interrupted mechanical testing method. To capture the internal ...
