Abstract
In tensile testing, non-standardized specimens are sometimes used to investigate the tensile characteristics. In this study, an effective method for investigating the tensile characteristics of such non-standardized specimens has been proposed. Two types of specimens made from ductile materials—standardized and non-standardized—were prepared and subjected to uniaxial tensile loads. The test results showed that there was a significant difference in the fracture strain when the non-standardized specimen was used. To evaluate the fracture strain, a new method that considered the absorbed strain energy distribution in the gauge section was proposed. Further, the validity of the proposed method was demonstrated by making comparisons with experimental results.
