地 点：深圳大学粤海校区（南区）致工楼C501
报告内容简介：
讲座将分为两个部分。第一部分分享了钱教授团队在测量焊接节点裂纹尺寸的先进无损检测（NDT）技术方面所做的研究，重点介绍了交流电位差（ACPD）和超声相控阵（UPA）等方法。演讲以这些无损检测结果为基准，介绍了一种物理信息化、数据驱动的数字孪生框架，用于确定焊接节点中表面裂纹的尺寸和形状。讲座的第二部分将讨论浮体结构的应用，包括其在下一代海岸保护基础设施中的挑战和研究机会。
This lecture will separate into two parts. The first part shares the journey, which the speaker’s research group has undertaken, in advanced nondestructive testing (NDT) techniques for measuring crack sizes in welded connections, focusing on methods such as Alternating Current Potential Difference (ACPD) and Ultrasonic Phased Array (UPA). Building on these NDT results as benchmarks, the presentation introduces a physics-informed, data-driven digital twin framework for determining the size and shape of surface cracks in welded connections. The second part of the talk will discuss the application of floating structures, including its challenges and research opportunities in the next generation coastal protection infrastructure.
