RISNonlinear Incompressible Finite Element for Simulating Loading of Cardiac Tissue—Part II: Three Dimensional Formulation for Thick Ventricular Wall Segments
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A three dimensional incompressible and geometrically as well as materially nonlinear finite element is formulated for future implementation in models of cardiac mechanics. The stress-strain relations ...
Nonlinear Incompressible Finite Element for Simulating Loading of Cardiac Tissue—Part I: Two Dimensional Formulation for Thin Myocardial Strips
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A two-dimensional incompressible plane-stress finite element is formulated for the simulation of the passive-state mechanics of thin myocardial strips. The formulation employs a total Lagrangian ...
Structural Three-Dimensional Constitutive Law for the Passive Myocardium
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A three-dimensional constitutive law is proposed for the myocardium. Its formulation is based on a structural approach in which the total strain energy of the tissue is the sum of the strain ...
