<div>Numerically obtained crack pattern and maximum crack widths [mm] due to the pressure imposed by expanding the bar in repair systems. Mortar is used as a repair material, influence of the substrate surface roughness, and the interface strength; top: repair material; bottom: substrate (deformation scaled 20x; note that for different samples maximum crack widths are different).</div>
