Web6 de jan. de 2016 · We previously reported that normal liver undergoes significant softening with the application of shear strain . We observe shear strain softening even for livers with established fibrosis, although the initial G' at minimal strain is significantly higher for fibrotic livers (Fig 4A–4C). Strain represents the displacement between particles in the body relative to a reference length. Deformation of a body is expressed in the form x = F(X) where X is the reference position of material points of the body. Such a measure does not distinguish between rigid body motions (translations and rotations) and chang…
