  • The blast resistance of sacrificial cladding has been extensively studied in the field of blast protection. As a polymer material with a cellular structure, non-water reactive foaming polyurethane also has the potential to act as a sacrificial cladding due to its good mechanical properties. In order to study the blast damage mitigation effect of polymer sacrificial cladding on reinforced concrete structures, a contact explosion test on the reinforced concrete slab with polymer sacrificial cladding was carried out, while an ordinary reinforced concrete slab was set as the control group, and the effect of polymer sacrificial cladding on the damage characteristics of the reinforced concrete slab was compared and analyzed. In addition, the SPH-FEM (coupled smooth particle hydrodynamics and finite element method) coupling model of the field explosion test was established by using AUTODYN software, and the reliability of the coupling model was verified by comparing with the test results. On this basis, the effects of explosive charge, the density, and the thickness of polymer sacrificial cladding on the damage features and energy absorption characteristics of reinforced concrete slabs with polymer sacrificial cladding were investigated through parametric sensitivity analysis. The results show that the polymer sacrificial cladding can effectively disperse the blast loads and mitigate the impact of the blast loads on the reinforced concrete slab with good protective performance under contact explosions. The polymer sacrificial cladding can maintain a high level of energy absorption even with the explosive charge increased within limits. Increasing the density and thickness of the cladding is beneficial to enhance the energy absorption ability of the polymer sacrificial cladding, while the change in thickness will cause a change in the damage mode of the protected reinforced concrete slab. The research results are helpful in providing a relevant reference for the further research and application of the new non-water reactive foaming polyurethane in the field of blast protection of engineering structures.
