The strain profile is assumed to be from a sensor attached to a reinforcement rebar.
The crack width calculation is carried out according to [2]. The tension stiffening component \(\varepsilon^{\mathrm{TS}}\) is provided by compensation.tensionstiffening.Berrocal. using the following calculation:
\[ \omega{}_{\mathrm{cr},i} = \int_{l_{\mathrm{eff,l},i}}^{l_{\mathrm{eff,r},i}} \varepsilon^{\mathrm{DOFS}}(x) - \rho \alpha \left(\hat{\varepsilon}(x) - \varepsilon^{\mathrm{DOFS}}(x)\right) \mathrm{d}x \]
Where \( \omega{}_{\mathrm{cr},i} \) is the \(i\)th crack and
