WHAT YOU SHOULD KNOW ABOUT FRACTURE TOUGHNESS

THE PRINCIPLES OF FRACTURE TOUGHNESS ARE BRIEFLY REVIEWED AND IT IS SHOWN THAT THE CONCEPTS OF FRACTURE MECHANICS CAN PROVIDE A QUANTITATIVE FRAMEWORK FOR EVALUATING STRUCTURAL RELIABILITY. FRACTURE TOUGHNESS, LIKE THE PROPERTIES OF TRANSITION TEMPERATURE, IMPACT STRENGTH, AND NOTCHED- UNNOTCHED STRENGTH RATIO, HELPS TO GAGE THE ABILITY OF A MATERIAL TO ARREST A CRACK THAT COULD CAUSE SUDDEN FAILURE BELOW THE YIELD STRENGTH. BUT UNLIKE THOSE OTHER PARAMETERS, FRACTURE TOUGHNESS SEEMS TO BE A MATERIAL CONSTANT, UNAFFECTED BY SPECIMEN GEOMETRY AND MORE RELIABLE IN PREDICTING RELIABILITY. /AUTHOR/
