✦ Synopsis

Several approaches to addressing ductile fracture are possible . The most common one is through the use of a global approach, which phrases the fracture resistance in terms of global parameters, such as J,' and S,-(CTOD) . Unfortunately, many works [1-4] have shown that J,C and S. are the specimen-geometry-dependence parameters in the case of plane strain . As fracture characterizing parameters, they should be material constants independent of the stress state . So, J,, and S. should be modified .

A general continuum damage mechanics (CDM) model for ductile fracture is proposed in the framework of CDM which can be reduced to linear and/or nonlinear models and can unify many known models by introducing appropriate values for the damage coeflicients of materials.

## Abstract In this paper, a modified up‐quenching heat treatment method for ASSAB 705M (AISI 4340) steel (ultra high strength steel) is proposed. A low alloy steel (0.33% C), was used to study the effect of isothermal austempering, successive austempering and modified up‐quenching austempering hea
