摘要
本文利用弹性理论对十字形试验板的应力分布进行了推导,并得出一个近似计算公式,结合电测实验进行校核,为直观起见,用有限元画出了该模型的应力等值线。
Some theoretical dervation had been made on the calculation of stress and strain of a cross-shaped experimental plate.An approximate calculating formula was put forward.Checked against the resuls of the strain gage method and the graphs of FEM,the formula was proved to be correct.
