1018 応力凍結法による偏荷重下のマンホール蓋の応力解析に関する研究(S04-1 実験力学における計測・解析法の新展開(1)光学的手法,21世紀地球環境革命の機械工学:人・マイクロナノ・エネルギー・環境)
詳細
The major part of stress analysis for a manhole cover is the numerical analysis. The experimental analysis was rarely done recently. In this research, the experimental analysis was done for the manhole cover using the stress frozen method. The stress concentration was confirmed at the edge of the load and the edge of the cover. The transmission of the load was confirmed on the cover including the rib under the partial load. It has been understood that careful corresponding is necessary in the shape and size of the volume fillet surface in the safety design.
