WebNov 25, 2009 · In both cases a subsized standard samples [38] with gage length of 1 in (25.4 mm) and width of 0.25 in (6.35 mm) were used for testing. Moreover, strain rate during testing was few orders of magnitude higher than in our study (3 × 10 −1 to 3 × 10 0 s −1 vs. 1 × 10 −3 s −1 ). Data comparison is shown in Table 1. Table 1. The preparation of test specimens depends on the purposes of testing and on the governing test method or specification. A tensile specimen usually has a standardized sample cross-section. It has two shoulders and a gauge (section) in between. The shoulders and grip section are generally larger than the gauge section by 33% so they can be easily gripped. The gauge section's smaller di…
