本文提出了实用而准确的公式来预测爆炸载荷下矩形无筋板和加筋板的结构损坏。本研究采用的数值计算方法使用已发表的测试数据进行了验证，然后对各种板模型进行了严格的参数研究。对参数研究结果进行回归分析，得出设计公式，从而产生板的残余损伤与冲击参数之间的线性关系。这些公式与现有公式进行了比较，并证实所提出的公式比其他公式更准确、更简单。
In this paper, practical yet accurate formulae are proposed to predict the structural damage of rectangular unstiffened and stiffened plates under explosion loads. The numerical computation method adopted in this study was validated using published test data and then, rigorous parametric studies were conducted for various plate models. Regression analyses of the parametric study results were performed to derive design formulae, which produced linear relationships between the residual damages of plates and an impact parameter. These formulae have been compared with existing ones and it is confirmed that the proposed ones are more accurate and simpler than others.
