Deformations associated with mild, physiological impact result in peak strains of up to 5%. The (dimensionless) strain fields shown (color bar) were superimposed over displacement fields in tagged images of the brain acquired during mild occipital impact. (a–c) Sagittal images. (a) Baseline shear strain, Exy (undeformed). (b) Normal strain, Exx. (c) Shear strain, Exy . (d–f) Transverse images. (d) Baseline shear strain, Exy (undeformed). (e, f) Deformed brain normal strain Eyy and shear strain Exy. Adapted from Reference 59.
