A new insight into plastic deformation behavior and its effect on pull-out failure of resistance spot welds during cross-tension testing

Key Points

• Resistance spot welds exhibit distinct plastic deformation behaviors during cross-tension testing, influencing their pull-out failure mechanisms.
• Increased pull-out resistance was observed in welds subjected to varying plastic deformation conditions, highlighting the importance of mechanical properties.
• Through cross-tension testing, observations were made regarding how different deformation behaviors affect failure rates during mechanical assessments.
• Understanding these behaviors may promote better design practices, ultimately enhancing the reliability and quality of welded structures.
