Investigating full-field deformation of planar soft tissue under simple-shear tests.

Finite simple shear test characteristics like specimen geometry and boundary conditions could affect the deformation homogeneity during the test. In order to ensure that the parameters of constitutive equations obtained from finite simple shear tests are appropriate, the deformation homogeneity of the specimen during simple-shear test should be examined. The Fourier transform moiré method (FTM) was used to examine the deformation uniformity of a porcine skin specimen in a finite simple shear test.
