Preliminary Analysis on the Influence of Lode Parameter on the Failure Strain

Lode parameter is important to describe the material stress status. To reveal the influence of Lode parameter on the failure strain, several kinds of tensile specimen were carried out. Meanwhile, the Lode parameter of specimen broken location were achieved by using numerical simulation method. The results indicated that Lode parameter could separately influenced the failure strain by contrasting the several specimen results under the same value of stress triaxiality.
