Simulation of single-fiber tension tests with rate-dependent material properties: (a) stress–strain diagram; and (b) the dynamic increase factor of the secant stiffness at fracture compared to experimental results from [5]. Material parameters used: $E=50$ kN/mm${}^2$, ${\alpha }^{\mathrm{I}}=0.19$ and ${\alpha }^{\mathrm{II}}=1.8\times {10}^{-3}$.
