The response of monolithic steel plates subjected to blast was extensively studied, and dozens of dimensionless numbers were proposed to predict the response. While the existing dimensionless numbers are not convenient to use in some scenarios with relatively complicated conditions, the dimensionless number proposed for blast loaded steel plates based on dimensional analysis extends the range of application. Different from other dimensionless numbers, the properties of medium with which the blast load transmits are incorporated to extend the application range to more general scenarios. The responses of the plate subjected to both near-field blast with non-uniform load and far-field blast with uniform load, i.e. both the external and internal blasts (for steel boxes), are reasonably predicted. The physical implication of the proposed dimensionless number is clear in that the media properties, geometrical features, characteristics of material, and loading are incorporated, which are readily available in test. A variety of test data are used to validate the applicability and versatility of the proposed dimensionless number.

爆破钢板响应的无量纲数

对整体钢板在爆炸作用下的响应进行了广泛的研究，并提出了数十个无量纲数来预测响应。虽然现有的无量纲数在一些条件相对复杂的场景中使用起来不方便，但基于尺寸分析提出的爆破钢板无量纲数扩大了应用范围。与其他无量纲数不同，结合爆炸载荷传递的介质特性，将应用范围扩展到更一般的场景。板在非均匀载荷近场爆炸和远场均匀载荷爆炸下的响应，即外部和内部爆炸（对于钢箱），是合理的预测。所提出的无量纲数的物理含义很明显，因为它包含了介质特性、几何特征、材料特性和负载，这些在测试中很容易获得。各种测试数据用于验证所提出的无量纲数的适用性和通用性。
