“…Due to the constraints of the material's hardness, toughness, tensile strength, and yield strength, the explosion and penetration resistances of steel are limited (Jacobs and Van Dingenen, 2001;Jena et al, 2010). Many scholars have found that PU can significantly enhance the explosion resistance (Ackland et al, 2013;Nemat-Nasser, 2010;Amini et al, 2010;Zeng et al, 2021) or anti-penetration performances (Mohotti et al, 2015(Mohotti et al, , 2014Huang et al, 2018 ) of metal structures. Dinesh et al (2021) conducted numerical simulations to study the anti-explosion performances of PU-reinforced steel plates with different coating methods and different coating thicknesses under the impact of different equivalent trinitrotoluene (TNT) explosives.…”

To investigate the effect of polyurea on the protective performance of a steel target plate under the combination of shock wave and fragments, the failure characteristics, damage process and micro mechanism of the polyurea coated steel plates with different coating methods under the combination of explosion shock waves and fragments were analyzed through experiments and numerical simulations. The results showed that single-sided coatings aggravated the damage of target plate when the coating thickness was 2 mm. While the polyurea thickness greater than 4 mm could significantly reduce the damage degree of the steel plate. When the polyurea was coated on the double sides, it would aggravate the damage, no matter how thick the polyurea was. Through microscopic research, it was found that the front coated polyurea was severely ablated by detonation products, which greatly reduce its energy absorption efficiency. The polyurea coated on the back underwent tensile fracture under the influence of tensile stress wave. The breaking of intramolecular hydrogen bond of polyurea was the key to the energy absorption of polyurea.
