International audience; The collagen response in rat Achilles tendons to in situ tensile loading was studied using small-angle X-ray scattering (SAXS), to evaluate the relationship between the elastic and viscoelastic behavior of the tissue and collagen fibrils. The fibril strains were substantially lower than the applied tissue strains. Fibril strains increased linearly before yielding and breaking prior to tissue failure.
