本文应用高灵敏度云纹干涉法在试验机上测定了带孔铝合金板的全场位移分量及其导数场,为云纹干涉法用于实测取得了初步经验。试验结果表明,在最小横截面上的弹塑性应变分布与电测法所得结果一致。
In this paper, we use the high-sensitivity moire interferometry method to measure the total displacement component and the derivative field of the perforated aluminum alloy plate on the testing machine, and obtain the preliminary experience for the moire interferometry. The experimental results show that the distribution of elasto-plastic strain at the minimum cross section is consistent with that obtained by the electrical measurement.
