 Plasticity effects on SE(B) specimens are more pronounced for shallow cracks and low hardening materials. Deviations in crack size estimations due to plasticity stayed within 5.5% for all conditions, which means a maximum of 8% deviation in crack size prediction. Additional modelling and experiments are being conducted.
