摘要

评估金属板的温度依赖性是至关重要的；然而，对于现代无损检测技术来说，这仍然是一个挑战。本文提出了一种非接触、非破坏性的方法，通过将s1 -零群速度共振与局部加热引起的捕获A1共振相结合来评估弹性模量的温度依赖性。谐振频率的测量使用了一个全光学实验系统，该系统集成了泵浦、探头和加热光束，在几个时间瞬间进行测量，从而可以同时评估杨氏模量和剪切模量的温度相关系数。利用差分演化技术将实验共振频率拟合到理论值，求解了反求问题，Ti-6Al-4V合金的反求结果与文献值吻合较好。

Measurement of temperature-dependent elastic moduli using S1-ZGV resonance and locally laser heating trapped A1 resonance

Evaluating the temperature dependence of metallic plates is vital; however, it remains challenging for modern nondestructive testing techniques. This paper proposes a non-contact, nondestructive method to evaluate the temperature dependence of the elastic modulus by combining the S1-zero-group-velocity resonance with the trapped A1 resonance induced by local heating. The resonance frequency was measured using an all-optical experimental system integrating a pump, a probe, and heating beams at several time instants, which enabled the simultaneous evaluation of the temperature-dependent coefficients of Young's modulus and shear modulus. The inverse problem was solved by fitting the experimental resonance frequency to the theoretical values using differential evolution techniques, and the inverted results for the Ti–6Al–4V alloy closely matched literature values.

期刊介绍： Applied Physics Letters (APL) features concise, up-to-date reports on significant new findings in applied physics. Emphasizing rapid dissemination of key data and new physical insights, APL offers prompt publication of new experimental and theoretical papers reporting applications of physics phenomena to all branches of science, engineering, and modern technology. In addition to regular articles, the journal also publishes invited Fast Track, Perspectives, and in-depth Editorials which report on cutting-edge areas in applied physics. APL Perspectives are forward-looking invited letters which highlight recent developments or discoveries. Emphasis is placed on very recent developments, potentially disruptive technologies, open questions and possible solutions. They also include a mini-roadmap detailing where the community should direct efforts in order for the phenomena to be viable for application and the challenges associated with meeting that performance threshold. Perspectives are characterized by personal viewpoints and opinions of recognized experts in the field. Fast Track articles are invited original research articles that report results that are particularly novel and important or provide a significant advancement in an emerging field. Because of the urgency and scientific importance of the work, the peer review process is accelerated. If, during the review process, it becomes apparent that the paper does not meet the Fast Track criterion, it is returned to a normal track.
