In order to create accurate anatomical models for medical training and research, mechanical
properties of biological tissues need to be studied. However, non-linear and viscoelastic …

The mechanical response of most soft tissue is considered to be viscohyperelastic, making
the development of accurate constitutive models a challenging task. In this article, we …

Understanding the mechanical properties of human liver is one of the most critical aspects of
its numerical modeling for medical applications or impact biomechanics. Generally, model …

The liver is the most commonly injured abdominal organ following either blunt or penetrating
impact. Current mechanical properties available in the literature are typically only measured …

Measuring the viscoelastic behavior of highly hydrated biological materials is challenging
because of their intrinsic softness and labile nature. In these materials, it is difficult to avoid …

Soft tissue mechanical characterisation is important in many areas of medical research.
Examples span from surgery training, device design and testing, sudden injury and disease …

Biological soft tissue is highly inhomogeneous with scattered stress–strain curves. Assuming
that the instantaneous strain at a specific stress varies according to a normal distribution, a …

Modelling the mechanical behaviour of biological tissues is of vital importance for clinical
applications. It is necessary for surgery simulation, tissue engineering, finite element …

Abstract A liver Finite Element (FE) model with hyper‐viscoelastic properties was developed.
Hyper‐elastic and rate‐dependent characteristics were modeled with an Ogden rubber …

This paper presents the results of recent investigations into the viscoelastic character of liver
tissue, especially the linear response. The linear domain of liver tissue has been determined …
