  • Title: Shear mechanical properties of the spleen: experiment and analytical modelling.
    Author: Nicolle S, Noguer L, Palierne JF.
    Journal: J Mech Behav Biomed Mater; 2012 May; 9():130-6. PubMed ID: 22498291.
    Abstract:
    This paper aims at providing the first shear mechanical properties of spleen tissue. Rheometric tests on porcine splenic tissues were performed in the linear and nonlinear regime, revealing a weak frequency dependence of the dynamic moduli in linear regime and a distinct strain-hardening effect in nonlinear regime. These behaviours are typical of soft tissues such as kidney and liver, with however a less pronounced strain-hardening for the spleen. An analytical model based on power laws is then proposed to describe the general shear viscoelastic behaviour of the spleen.
