Computation for gage length and measurable frequency of strain wave using the strain gage 应变计栅长与可测应变波频率计算
The error created by sample ′ s length and the gage length, is modified with a complementary value. 由试样长度与标距不一致产生的测量偏差,可通过补偿值加以修正,其测量精度与常规测量方法基本相同。
Analysis for the stress magnification of dog-bone-shaped specimen shows that the stress magnification coefficient increases obviously with the reducing of gage diameter, and it increases with the reducing of gage length. 分析狗骨形试样应力放大系数表明,应力放大系数随着试样中间等截面段直径的减少会有显著增加,随着试样中间段长度的增加,应力放大系数也相应降低。
