"Shear waves in prestrained poroelastic media." 13th International Conference on Mathematical and Numerical Aspects of Wave Propagationhttps://hdl.handle.net/2144/30039Shear wave elastography measures shear wave speed in soft tissues for diagnostic purposes. In [1], shear wave speed was shown to depend on prestrain, but not necessarily prestress, in a perfused canine liver. We model this phenomenon by examining incremental waves in a pressurized poroelastic medium with incompressible phases. The analysis suggests novel restrictions on the strain energy functions for soft tissues.Incremental wavesBiomedical engineeringMechanical engineeringPoroelasticityStrain energy functionElastographyConference materials
