    Crack growth instability, or sudden fracture, would occur when these parameters reached their “critical” values. These values represent the material property conjugate to the crack-driving forces (G or K), i.e., the fracture toughness. With the present state of understanding, fracture toughness cannot be calculated based on other mechanical @article{osti_, title = {Kinetics of [gamma][prime] precipitation and its influence on fatigue crack growth behavior of a new single-crystal nickel-based superalloy (CMSX-4G) at room temperature}, author = {Sengupta, A and Putatunda, S K}, abstractNote = {An investigation was carried out to determine the growth kinetics of [gamma][prime] precipitates in a newly developed single-crystal

The Griffith criterion states that ”crack growth will occur, when there is enough energy available to generate new crack surface.” The energy release rate is an essential quantity in energy balance criteria.
