带裂纹矩形板在动载下破裂的试验研究

Fracture Testing Study of Rectangular Plates with Cracks under Dynamic Loading

本文详细描述了带裂纹的矩形石膏板在动载作用下裂纹的起裂、扩展、破坏的全过程。根据断裂动力学和应力波理论,对其试验结果进行了分析,得出带裂纹石膏板试件在动载作用下产生破裂所遵循的规律。

In this paper, the whole process of initiation, propagation, and failure of rectangular plaster plates with cracks under dynamic loading is described in detail. Based on the theories of fracture dynamics and stress wave, the testing results are analysed, and the fracture law followed by the plates with cracks under dynamic loading is given.
