            我院舉辦“Direct Determination of Dynamic Elastic Modulus and Poisson's Ratio of Timoshenko Prisms”學術報告會

                12月16日上午betway体育,“Direct Determination of Dynamic Elastic Modulus and Poisson's Ratio of Timoshenko Prisms”學術報告會在土木樓212報告廳舉行。本期學術報告會主講人為美國西弗吉尼亞大學結構工程學Hung-Liang Chen教授,報告會由西安建筑科技大學土木工程學院門進杰教授主持,土木工程學院部分教師及近百名研究生參加了本期報告會betway体育。

                  門進杰教授介紹

            門進杰教授主持報告會

            在門進杰教授向大家簡要地介紹主講人后,同學們熱烈地歡迎Hung-Liang Chen教授上臺做演講。陳教授首先表達了對于來到我校的喜悅心情betway体育,然后開始做學術報告。報告分為了七個內容:1)介紹betway体育,2)NDT無損檢測方法,3)鐵木辛柯梁震動模型,4)模型分析,5)測定實驗介紹betway体育,6)實驗數據分析,7)結論。

                  陳洪亮教授作報告

            Hung-Liang Chen教授首先講述了準確測量彈性模量和泊松比對于確眀etway体育;炷两Y構的結構完整性的重要性,并向大家介紹了ASTM C215-14這一種無損檢測方法。Hung-Liang Chen教授在報告中提出了一種共振頻率與泊松比之間的關系式。與工業標準提供的方程不同,這種關系式可以直接同時確定彈性模量和泊松比betway体育,無需迭代。這個關系式可以直接估計試件的第一彎曲模態和扭轉模態之間的頻率比。

            然后betway体育,Hung-Liang Chen教授介紹了如何用實驗方法計算泊松比和動態彎曲頻率比的彈性模量,并分析了實驗的可行性betway体育。在自由邊界條件下betway体育,用精確的剪切形狀因子確定了鐵木辛柯梁振動頻率方程的精確解。將精確解與ABAQUS三維有限元計算結果進行了比較betway体育betway体育,結果表明,精確解與三維有限元計算結果的差異在0.05%以內。

            Hung-Liang Chen教授所做的報告邏輯嚴謹、條理清晰,為我院研究生在科研道路的探究過程中做了很好的榜樣,對于促進我院師生國際學術交流和學習具有重要的促進作用betway体育。

             

             

            報告人介紹:

             Dr. Hung-Liang (Roger) Chen received his M.S. and Ph.D. in structural engineering from Northwestern University, Evanston, IL, in 1985 and 1988, respectively. He joined West Virginia University in 1989 as an Assistant Professor and was promoted to Associate Professor with Tenure in 1995 and Professor in 2000. He has been involved extensively with research in structural dynamics, nondestructive evaluation (NDE), dynamic soil-structure interaction, and material characterization of concrete, composites, timber, and ceramic materials. He also has ongoing research in mass concrete, self-consolidating concrete, GFRP-reinforced CRCP, and NDE of wellbore cement. Dr. Chen has more than 150 technical publications and has received over 40 research awards with a total of about 4.7 million dollars as Principal Investigator. He has advised over 45 graduate students, including 11 Ph.D. students. He is active on several technical committees for the American Concrete Institute, the American Society of Civil Engineers, and the American Society for Nondestructive Testing (ASNT). He has received numerous honors and awards for his contributions in teaching and research. Dr. Chen is a Fellow of ASNT.
