摘要
此文用直接法和间接法研究了δ值和计算方法对γ值的影响。发现γ值基本上与δ无关。δ只影响其测量精度,δ愈大愈有利于提高γ的测量精度。计算方法对γ值的影响只在δ值较小时。随δ增大,计算方法的影响逐步消除。
The influence of plastic strains (δ) and computing methods on the plastic strain ratios (γ) has been studied by both the divect method and the indircet method in the present investigation. The γ-Value is almost not relative to the δ-Value. The δ-Value only affects the measure precision of γ-Value. The larger the δ-Value is, the higher the precision of γ-Value is. The computing methods influence the γ-Valur only when the δ-Value was smaller. The effect of the computing methods decreases gradually while the δ-Valur increases.
