Material Property: Fracture Toughness
Material Property: Fracture Toughness
(OP)
Could anyone point me to a formula or other relation that specifically relates Notched Izod Impact Strength [J/cm] to Fracture Toughness [MPA-m^1/2]. If it also relates Charpy I'd consider it a bonus.
Is this a direct relation? Is fracture Toughness derived from the Izod or Charpy testing methods?
I've done some online and offline searches but no formulas are presenting themselves.
Thanks in advance.
