利用霍普金森杆束对混凝土的动态行为进行了广泛的实验研究。为了研究内部相对湿度对不同应变率下混凝土拉伸行为的影响，对一些试件进行了三种不同的养护条件，然后在准静态、软冲击载荷和硬冲击载荷下进行了测试。还提出了一种物理方法来解释观察到的强度变化。
A wide experimental study on dynamic behaviour of concrete has been carried out by means of the Hopkinson Bar Bundle. In order to study the effect of the internal relative humidity on the tensile behaviour of concrete loaded at different strain-rates, some specimens have been subjected to three different curing conditions and then tested under quasi-static, soft and hard impact loads. A physical approach is also proposed to explain the observed variation in strength.
