<div>Numerically obtained crack pattern and maximum crack widths due to the pressure imposed by expanding bar in repair systems. Substrate is stronger than repair material and influence of interface strength; top: repair material; bottom: substrate (note that for different samples maximum crack widths are different).</div>
