英文摘要	As one of the protective components, the high strength low alloy structural steel plate had attracted extensive attention because of frequent threats of explosive loads. In this paper, combining explosion experiment, finite element model (FEM) and multi-scale microscopic observation technique, the relationship between macroscopic dynamic response and microscopic damage of low alloy steel plate under the close-range explosion (i.e., 2 cm, 3 cm, 6 cm, and 10 cm) was investigated. After the explosion experiments and validation of the FEMs of the four steel plates, the thickness sections of the position closest to the explosives were selected for microscopic observation of different scales. According to the observation results, the defects were characterized and mainly divided into four damage types. Subsequently, based on the numerical simulation data and microscopic observation results, three models were established to describe the change rules of impulse-explosive distance (I-E), texture-explosive distance (T-E), as well as impulse-texture (I-T), respectively. The results showed that when the explosive distance was 2-10 cm, I-E and T-E were consistent with the quadratic fit. In addition, the texture of base material (BM) was 3.42, which was 2.36 times larger than that of closest explosive distance sample. The variation law of I-T better revealed the relationship between the macroscopic dynamic response and microscopic damage with different explosive distances which agreed with the linear model. These results can be used to predict and prevent damage propagation of low alloy steel plate under the close-range explosion and improve the protective ability of protective materials.
