图8 纳米孪晶Cu屈服强度的计算结果与实验结果的对比[49] (a) the fraction of yielded grains as a function of applied stress for representative nt-Cu samples with twin thicknesses of 5, 15, 40, and 100 nm. Yield strength of the sample is defined as the stress at which the fraction of yielded grains reaches 99% (Inset is the schematic for evaluating yield strength of nt-Cu using the Sachs model) (b) calculated yield strength as a function of twin thickness as compared with experimental results
