應yl7703永利官網黃玉梅教授的邀請，中山大學珠海校區(qū)數(shù)學學院劉海峰副教授將于近期訪問我校并作學術報告,歡迎廣大師生參加。

報告題目：Structural Damage Detection via Compressive Sensing

時間：2024年7月22 日 上午10: 00 -12:00

地點：理工樓518報告廳

Abstract：The generalized flexibility matrix method can detect structural damage by using a small number of natural frequencies and corresponding mode shapes. However, during the process of the structural dynamic test, the mode shapes are usually measured at a part of the structure and their values at rotation are difficult to be achieved. Thus, involved mode shapes are incomplete for most cases. This results in a challenge for the damage detection. This talk concentrates on the structural damage detection problem with incomplete mode shape data. The idea of sparse representation is utilized. Two numerical examples are given to show the effectiveness of our method only using several translational deflection data.
