Simple empirical model for identifying rheological properties of soft biological tissues.
Understanding the rheological properties of soft biological tissue is a key issue for mechanical systems used in the health care field. We propose a simple empirical model using fractional dynamics and exponential nonlinearity (FDEN) to identify the rheological properties of soft biological tissue. The model is derived from detailed material measurements using samples isolated from porcine live...
متن کاملIdentifying a minimal rheological configuration: a tool for effective and efficient constitutive modeling of soft tissues.
We describe a modeling methodology intended as a preliminary step in the identification of appropriate constitutive frameworks for the time-dependent response of biological tissues. The modeling approach comprises a customizable rheological network of viscous and elastic elements governed by user-defined 1D constitutive relationships. The model parameters are identified by iterative nonlinear o...
متن کاملA variational constitutive model for soft biological tissues.
In this paper, a fully variational constitutive model of soft biological tissues is formulated in the finite strain regime. The model includes Ogden-type hyperelasticity, finite viscosity, deviatoric and volumetric plasticity, rate and microinertia effects. Variational updates are obtained via time discretization and pre-minimization of a suitable objective function with respect to internal var...
متن کاملElasticity of soft tissues in simple elongation.
FUNG, Y. C. B. Elasticity of soft tissues in simple elongation. Am. J. Physiol. 213(6) : 1532-l 544. 1967 .-Elasticity of living soft tissues is strongly nonlinear. Based on experimental results on rabbits’ mesentery, a theoretical framework is presented in which the elastic properties of soft tissues can be described. It is shown that the mathematical formulation works well also in reducing pu...
متن کاملMechanical Properties of Biological Tissues
The material response discussed in the previous chapters was limited to the response of elastic materials, in particular to linearly elastic materials. Most metals, for example, exhibit linearly elastic behavior when they are subjected to relatively low stresses at room temperature. They undergo plastic deformations at high stress levels. For an elastic material, the relationship between stress...
