heat straightening repair cycles on the structural properties and fracture toughness of various bridge steels (A36, A588, and A7). The damage and repair parameters included in the study were the damage strain (εd), the restraining stress (σr), the number of damage-heat straightening repair cycles (Nr), and the maximum heating temperature (Tmax). The research project was conducted in two phases.

Fracture Toughness of Metal Castings IntechOpen

The fracture toughness values range from about 25 MPa m 1/2 in an iron with yield strength of about 450 MPa to nearly 60 MPa m 1/2 in an iron of yield strength of 370 MPa . It is possible that the intrinsic fracture toughness of nodular iron would be higher if the inherent shrinkage, among the highest in cast irons, is reduced.

Requirements for Impact testing A36 or A992 at -40¦C ...

Dec 12, 2007 · In a nutshell, one of the reasons that A36 is not recommended for "low temperature service" is the inherent risk of brittle fracture because of the low toughness of this material (below -20 deg C) supplied under ASTM/ASME A/SA 36 with no impact requirements. By the way, you don't need dynamic loads to induce brittle fracture in a structure.

Fracture toughness databases are often used to get an estimate of the toughness of materials in an existing structure, from which it is difficult or impossible to extract specimens. It is important to be aware that a fracture toughness database gives only an example of the toughness measured in a given material under particular conditions (such as specimen thickness, heat treatment and test temperature).
