The objective of this work is to examine the utility of so-called modified path-independent integrals, referred to as “integral parameters” in this paper, for the prediction of crack growth at elevated temperatures where the crack tip deformation

Integral parameters J * and Jˆ are used to predict crack growth under R e = 0 strain cycling with hold time at the maximum strain. Both nominally elastic and nominally plastic strain levels are investigated. Test data are obtained for single edge no

Linear elastic fracture mechanics approaches are not suitable for prediction of fatigue crack growth in the nonlinear regime at elevated temperatures. The objective of this paper is to investigate the ability of the integral parameters by Blackburn (

This paper investigates the utility of the rate forms of Kishimoto et al.'s integral (Ĵ) and Blackburn's integral (J*) as parameters for correlating time-dependent crack growth rates. These rate integrals are computed from the results of finite elem

In a study of plastic fracture in five high-strength aluminum alloys (2014, 2024, 2124, 7075, and 7079), it has been shown that fracture toughness is affected primarily by the size and volume fraction of the larger (2 to 10 microms) second-phase part

The plane strain fracture toughness K sub Ic and conventional tensile properties of two commercially produced one-inch thick Ti-5Al-2.5Sn plates were determined at cryogenic temperatures. One plate was extra-low interstitial (ELI) grade, the other no

As surface flaws grow in high-strength nickel-base superalloys, the growth along the free surface (dc/dN) can be much slower than growth in the depth direction (da/dN), even after accounting for variations in K along the crack front. This behavior re

Accurate crack growth prediction methods are playing an increasing role in the design and evaluation of rotating gas turbine engine components. Fracture mechanics methods used to predict the cyclic lives (without time-dependent effects) are well esta

This paper contains an extension of the uniaxial state variable constitutive model of Ramaswamy et al. (1988) to the case of multiaxial loading. The correlation between uniaxial and multiaxial loading conditions is achieved through the assumptions of
