Abstract Fracture in fluid-saturated porous solids is governed not only by solid mechanics but also by fluid flow within the pore space. In systems ranging from geomaterials to biological tissues, deformation in the near-tip region perturbs pore pressure and thereby alters crack growth. Yet these pore-fluid effects have largely been inferred rather than directly observed. Here, we perform in situ pore-pressure measurements during controlled tensile rupture of a water-saturated microporous cement.
