  Hello
  I face burr issue due to plastics melt after ultrasonic welding.
  The ultrasonic vibration creates friction between welding interface.
  This friction creates heat which will cause a melt and flow in the plastics material.
  How can I simulate this phase change of plastics melt?
  Are there any introduction or training documents? Thank you!
