(A) Stress–strain curve and (B)–(D) example tomographic data acquired during a triaxial deformation experiment using thermally damaged Ailsa Craig microgranite (scale bar = 850 µm) at the PSICHÉ beamline, Synchrotron Soleil. Strain data in (A) were determined directly from the reconstructed images acquired at static stress points during loading. The tomographic slices shown are cut parallel to the principle stress axis (σ1) and show the progressive development of microfractures from (B) 7 MPa differential stress, (C) through 162 MPa differential stress, (D) to 185 MPa peak differential stress just prior to shear failure.
