    • An X-ray cell for the acquisition of one-dimensional mechanical force-displacement diagrams of soft tissue samples has been developed. The combination of X-ray and mechanical data allows new insights into the coupling of the macroscopic behavior and nanoscopic structural changes during the application of load. Two linear mu-translation stages are used to symmetrically - i.e. bidirectionally - stretch the sample. A video-extensometer is installed to record geometrical changes of the sample during measurement which allows to determine true stresses and strains. The sample can be immersed in a liquid and heated. We demonstrate the advantages over common unidirectional tensile testing devices without length measurement systems by comparing different mechanical and diffraction data sets of human arterial tissue.

  • In situ tensile testing of human aortas by time-resolved small-angle X-ray scattering
  • 2005
  • Ingår i: Journal of Synchrotron Radiation. - 0909-0495 .- 1600-5775. ; 12, s. 727-733
  • Tidskriftsartikel (refereegranskat)abstract
    • The collagen diffraction patterns of human aortas under uniaxial tensile test conditions have been investigated by synchrotron small- angle X- ray scattering. Using a recently designed tensile testing device the orientation and d- spacing of the collagen fibers in the adventitial layer have been measured in situ with the macroscopic force and sample stretching under physiological conditions. The results show a direct relation between the orientation and extension of the collagen fibers on the nanoscopic level and the macroscopic stress and strain. This is attributed first to a straightening, second to a reorientation of the collagen fibers, and third to an uptake of the increasing loads by the collagen fibers.
