Hi all! I am trying to understand the stress vs strain plot for my model. I am using Abaqus/Explicit so 'LE' is the strain that I selected for output. I am trying to understand the trend of stress vs LE plot. Why am I getting opposite that expected? Can anyone please help me to understand this? The loading and unloading branch are mirror image of what I am expecting. Also, why I am getting positive strain?
