Incorporating Mullins Effect into the Modeling of Hyperelastic Actuators
… study was performed to calibrate a hyperelastic pressure-volume relationship for thin-walled cylinders with Ogden-Roxburgh damage. Included in this model is a fractional multiplier to capture the convergence of stress softening after roughly 10 cyclic loadings. The Ogden-Roxburgh model was …

Muscle Metaboreflex Control Of Coronary Blood Flow And Ventricular Contractility During Dynamic Exercise In Normal And Heart Failure Conditions
… and n=7, heart failure) and measured arterial pressure (MAP), cardiac output (CO), circumflex blood flow (CBF), and calculated coronary vascular conductance (CVC), maximal derivative of ventricular pressure (dp/dt), and preload recruitable stroke work (PRSW) at rest and during mild exercise …

Sex dimorphism in the cardiometabolic effects of the smoothelin-like 1 protein deletion in an ageing mouse model
… and female) was assessed by echocardiography and pressure-volume loop, and the metabolic measurements of middle-aged animals (12-month-old, male and female) were carried out in the comprehensive lab animal monitoring system (CLAMS). The cardiac hemodynamic profiling showed that young male SMTNL1 …

Development of a Micromorphic (Multiscale) Material Model aimed at Cardiac Tissue Mechanics
… shear experiments [80], and subsequently, to a pressure-volume relationship. The contribution of the micromorphic additional degrees of freedom to the various triaxial shear modes is quantified, and an analytical explanation is provided for differences in contributions. The passive filling phase …

Computational modeling of the tissue mechanics in rheumatic heart disease patients
… coefficients, fiber angles, and diastolic pressures aimed to minimize the error between the Klotz curve and the simulated end-diastolic pressure-volume relationship (EDPVR) curve for each subject. Beginning with the unloaded left ventricular volume (V0), optimization progressed until the …

Modelling cardiopulmonary interactions. Towards anatomically detailed and physiologically accurate cardiorespiratory models
… both for a linear and nonlinear end diastolic pressure volume relationship), pulmonary circulation, lungs, peripheral terminals and gas exchange. We propose a first and a second order numerical method for the solution of the 1D coupled blood flow-transport problem, examining the numerical …

Maternal Vascular Compliance of Placentas in Rabbits
… in order to determine placental maternal blood volume. Maternal pressure was measured by means of catheters placed in femoral arteries and veins and recorded on a piethysmograph. Adjustable ties were placed around the maternal inferior vena cava and aorta so that pressures could be altered. A …

A Computational Model of Inert Gas Mixing in the Lung
… flow distribution based solely on parenchymal volume, progressing through flow distributions based on non-linear relationships between parenchymal pressure and parenchymal volume, to coupled models of the airway resistance and parenchymal distortion (including dependence on viscosity and …
