A Theory for Transverse Deflection of Poroelastic Plates
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A theory is presented for the bending of fluid-saturated poroelastic plates. The governing equations, based on linear consolidation theory, reduce to a single fourth-order integro-partial-differential ...
Large-Strain Behavior of Unsymmetric Laminates
Publisher: The American Society of Mechanical Engineers (ASME)
Biomechanics of Growth, Remodeling, and Morphogenesis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This review deals with biomechanical aspects of growth (mass change), remodeling (property change), and morphogenesis (shape change) in living systems. The emphasis is on theoretical models, but ...
Stress-Modulated Growth, Residual Stress, and Vascular Heterogeneity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A simple phenomenological model is used to study interrelations between material properties, growth-induced residual stresses, and opening angles in arteries. The artery is assumed to be a ...
Material Properties and Residual Stress in the Stage 12 Chick Heart During Cardiac Looping
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: During the morphogenetic process of cardiac looping, the initially straight cardiac tube bends and twists into a curved tube. The biophysical mechanisms that drive looping remain unknown, but ...
Computational Model for the Transition From Peristaltic to Pulsatile Flow in the Embryonic Heart Tube
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Early in development, the heart is a single muscle-wrapped tube without formed valves. Yet survival of the embryo depends on the ability of this tube to pump blood at steadily increasing rates ...
On the Effects of Residual Stress in Microindentation Tests of Soft Tissue Structures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Microindentation methods are commonly used to determine material properties of soft tissues at the cell or even sub-cellular level. In determining properties from force-displacement (FD) data, it ...
A Nonliner Poroelastic Model for the Trabecular Embryonic Heart
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A theoretical model is presented for the primitive right ventricle of the stage 21 chick embryo. At this stage of development, the wall of the heart is trabecular with direct intramyocardial ...
Viscoelastic Material Properties of the Myocardium and Cardiac Jelly in the Looping Chick Heart
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Accurate material properties of developing embryonic tissues are a crucial factor in studies of the mechanics of morphogenesis. In the present work, we characterize the viscoelastic material ...
Automatic Generation of User Material Subroutines for Biomechanical Growth Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The analysis of the biomechanics of growth and remodeling in soft tissues requires the formulation of specialized pseudoelastic constitutive relations. The nonlinear finite element analysis package ...
