人工缺陷可以通过受控的热疲劳载荷来制造。产生的裂纹可以引入到多种材料中。该技术还提供了一个独特的机会来监测热加载过程中裂纹的超声波响应。本文报告了不同热载荷循环对超声响应影响的研究。使用 FEM 分析载荷。两个裂纹样品承受不同的热载荷循环。
Artificial flaws can be manufactured by controlled thermal fatigue loading. The produced cracks can be introduced to a wide variety of materials. This technology gives also a unique opportunity to monitor the ultrasonic response of a crack during thermal loading. This paper reports studies on the effects of different thermal load cycles on the ultrasonic response. The loads are analyzed with FEM. Two cracked samples were loaded with different thermal load cycles.
