Abstract  The temperature dependence of fracture toughness of materials seems to haveanalogy to that of yield strength.This similarity for low-carbon steel has beenapproached on the basis of the plastic work loss at the crack tip.Both obey theexponential law and are in agreement with experiment.The availability to enquirefor the temperature dependence of fracture toughness for certain materials otherthan low-carbon steel from that of yield strength has been also discussed.
