Fig. 3From: Impact resistance of steel materials to ballistic ejecta and shelter development using steel deck platesNominal stress-strain relationship for SUS304 (Fukui et al. 2017) and SS400 (Yamada et al. 2016). Strain rate from 10−4 to 10−2 s−1 was obtained from quasi-static test; strain rate of 102 s−1 was obtained from high-strain-rate test. Due to the limited capacity of the testing apparatus, the impact test could not be carried out until fracture. Therefore, the curves end with arrows in the figureBack to article page
