The von-Mises stress, core result shows the von-Mises stress in the core at ejection.
This result is output from a Core-shift Warp or Stress analysis. Use this result when the material is ductile.
Areas with high levels of stress shows increased areas of fatigue on the core, which can lead to the core cracking and the part failing.
You can use the von-Mises stress, core result to ensure the areas with the maximum stress are below the relevant material criteria. Ensuring that the von-Mises stress, core values are low overall decreases the chance of part failure.
