摘要

利用时间反转原理对具有结构单元代表性的均质金属梁在不同健康状态下的损伤进行检测。然后，使用损伤指标对检测到的损伤进行量化。结果表明，即使换能器数量有限，超声波频率有限，例如，30 kHz左右，损伤也是可以检测到的。这项研究是监测土木工程结构元件，如桥梁电缆，在其早期发展中检测其损伤的第一步。

On the damage detection of a metallic beam based on the time reversal principle

The time reversal principle is exploited for damage detection of a homogeneous metallic beam, representative of a structural element, at its different health states. Then, a damage index is used for quantifying detected damages. It is shown that even with a limited number of transducers and restricted ultrasonic frequencies e.g., around 30 kHz, the damages are detectable. This study, is a primary step for monitoring civil engineering structural elements such as bridge cables for detection of their damages at their early developments.

期刊介绍： Archives of Civil and Mechanical Engineering (ACME) publishes both theoretical and experimental original research articles which explore or exploit new ideas and techniques in three main areas: structural engineering, mechanics of materials and materials science. The aim of the journal is to advance science related to structural engineering focusing on structures, machines and mechanical systems. The journal also promotes advancement in the area of mechanics of materials, by publishing most recent findings in elasticity, plasticity, rheology, fatigue and fracture mechanics. The third area the journal is concentrating on is materials science, with emphasis on metals, composites, etc., their structures and properties as well as methods of evaluation. In addition to research papers, the Editorial Board welcomes state-of-the-art reviews on specialized topics. All such articles have to be sent to the Editor-in-Chief before submission for pre-submission review process. Only articles approved by the Editor-in-Chief in pre-submission process can be submitted to the journal for further processing. Approval in pre-submission stage doesn''t guarantee acceptance for publication as all papers are subject to a regular referee procedure.
