The method is being developed for A measuring biomechanics associated with root growth by using B cone penetrometer root analogs for C correlated X-ray computed tomography (XCT) and X-ray diffraction (XRD). D Diamond Light Source and diagram of the experimental setup for the correlated XCT and XRD measurements at the DIAD beamline. E Developed in-situ compression rig with F the cone penetrometer and sample near the detector using a root analog cone. G Overlaid XCT and XRD result from DIAD-reconstructed 3D image and 2D diffraction map representing the ensemble of inferred stress values across the sample. H Diagram of the mathematical mechanical model domain and the associated boundary conditions simulating the experiment.
