摘 要:本文介绍了用摆锤冲击测量材料动态断裂韧度K1d的方法,并以不同贴片方案测试说明支座传感器方法波形回零好,便于数据处理。同时,以ZL201为例说明测试和数据处理时应考虑的问题。
Abstract: This paper introduces the method of determining materials’ dynamic fracture toughness K1λ by the impact pendulum and through various strain-gauge distribu- tions of surveying schemes explains that the support transducer method has a merit of good returning to zero as about the wave pattern, hence, being convenient to the data-treatment. Meanwhile, taking material ZL201 as an example, it explains the problems should be considered in the course of surveying and data-treatment.
