Based on the adoption of elastoplastic damage theory and effective strain assumption, weld metal coupons were tested under repeated pull and their damage evolution law was determined.
基于各向同性弹塑性损伤假定和应变等效假设,采用重复拉伸的试验方法,得到了焊缝金属的损伤演化规律。

Under the assumption of equivalent strain principle, a damage constitutive model is established based on Mohr-Coulomb criterion.
