Protecting infrastructures against blast loads from terrorist bombing or accidental explosion is a challenge. Researchers have been working on developing a numerical model, but the progress is slow owing to difficulties in modelling nonlinear and high strain rate damage process. Most blast effect assessment is based on empirical relations from blast tests. These have been demonstrated not necessarily yielding accurate prediction owing to variations of structural properties from the test model. A reliable numerical model is therefore important. It will result in big savings from blast tests, and better prediction of blast effects for structure and occupant protection. It will have applications in civil, mining and defence engineering.

保护基础设施免受恐怖主义爆炸或意外爆炸的冲击载荷是一项挑战。研究人员一直致力于建立一个数值模型，但由于非线性和高应变率损伤过程难以模拟，进展缓慢。大多数爆炸效应评估是基于爆炸试验的经验关系。这些已被证明不一定产生准确的预测，由于测试模型的结构特性的变化。因此，可靠的数值模型非常重要。这将大大节省爆炸试验费用，并能更好地预测爆炸对结构和乘员的影响。它将应用于民用、采矿和国防工程。
