文摘

•: Numerical instability during cohesive zone modeling under constant displacement is derived for the first time.
•: Plastic material behavior is included in the revisit to the “snap-back” issue.
•: The effect of viscous regularization on symmetry modeling is discussed.
•: Effectiveness of the viscous regularization under constant displacement is proved by a hydrogen embrittlement case study.
