本文研究了混凝土在四点弯曲状态下的声发射特性。不同含量的钢纤维被用作混凝土板中的增强体，并研究了它们对断裂过程和声活性的影响。总声发射（AE）活动被发现是成正比的纤维含量。分析表明，特定的声发射参数随损伤的进展单调变化，可以用来表征破坏过程。
The present paper describes the acoustic emission (AE) behavior of concrete under four-point bending. Steel fibres of varying content were used as reinforcement in concrete slabs and their influence on the fracture process and the acoustic activity was investigated. The total acoustic emission (AE) activity was found to be directly proportional to the fibre content. Analysis revealed that particular AE parameters change monotonically with the progress of damage and can be used for the characterization of the failure process.
