Abstract

It is shown that in the expansion of the crack opening displacement vs distance from the tip, there is no linear term present. This should lead to improved accuracy of the near tip fields and improved stress intensity factor results. The two-dimensional discussion should be able to be carried over to three dimensions.

Crack tip interpolation, revisited

Journal Article Gray, L J ; Paulino, G H - SIAM Journal of Applied Mathematics

It is well known that the near tip displacement field on a crack surface can be represented in a power series in the variable {radical}r, where r is the distance to the tip. It is shown herein that the coefficients of the linear terms on the two sides of the crack are equal. Equivalently, the linear term in the crack opening displacement vanishes. The proof is a completely general argument, valid for an arbitrary (e.g., multiple, nonplanar) crack configuration and applied boundary conditions. Moreover, the argument holds for other equations, such as Laplace. A limit procedure for calculating the surfacemore »« less

Determining fatigue crack opening loads from near-crack-tip displacement measurements

Conference Riddell, W T ; Piascik, R S ; Sutton, M A ; ...

The aim of this research was to develop a near-crack-tip measurement method that quantifies crack closure levels in the near-threshold fatigue crack growth regime--a regime where crack closure is not well characterized by remote compliance methods. Further understanding of crack closure mechanics was gained by performing novel crack growth experiments in conjunction with numerical simulations of three-dimensional crack-front propagation. Steady-state (i.e., constant growth rate) fatigue crack growth rates were characterized by performing constant cyclic stress intensity range ({Delta}K) experiments over a wide range of stress ratios (R). Near-crack-tip (less than 0.3 mm behind) load-versus-displacement measurements were conducted on the specimenmore »« less
Fracture surface interference in shear. 2: Experimental measurements of crack tip displacement field under Mode II loading in 7075-T6 Al

Journal Article Gross, T S ; Watt, D W ; Zhang, Y - Acta Metallurgica et Materialia

The in-plane and out-of-plane displacement field around the tip of a crack (produced by Mode I fatigue precracking) loaded in pure, remote Mode II was measured as a function of K{sub IIapp} by electro-optic holographic interferometry. The effective Mode II stress intensity factor and the induced Mode I stress intensity factor were estimated from a fit to the near-tip expressions for the crack face displacement fields. The effective Mode II stress intensity factor was always less than the applied stress intensity factor demonstrating that the fracture surface asperities shield the crack tip. The induced Mode I stress intensity factor wasmore »« less

Finite deformation analysis of crack tip opening in elastic-plastic materials and implications for fracture initiation

Technical Report McMeeking, R M

Analyses of the stress and strain fields around smoothly blunting crack tips in both non-hardening and hardening elastic-plastic materials, under contained plane strain yielding and subject to mode I opening loads, have been carried out by a finite element method suitably formulated to admit large geometry changes. The results include the crack tip shape and near-tip deformation field, and the crack tip opening displacement has been related to a parameter of the applied load, the J-integral. The hydrostatic stresses near the crack tip are limited due to the lack of constraint on the blunted tip, limiting achievable stress levels exceptmore »« less

Fracture toughness of line pipe steels under cathodic protection using crack tip opening displacement tests

Journal Article Hagiwara, N ; Oguchi, N - Corrosion

A series of crack tip opening displacement (CTOD) tests were carried out for evaluation of hydrogen stress cracking (HSC) of pipelines under cathodic protection. In the buffer solution, the critical CTOD ([delta][sub c]) of API 5L X65 line pipe steels was dependent on the CTOD testing mode (constant load rate testing and constant displacement rate testing) and also on the testing rate. [delta][sub c] decreased drastically when 1 mA/cm[sup 2] < cathodic current density (i) [le] 2 mA/cm[sup 2] and depended less on i when i [ge] 2 mA/cm[sup 2]. [delta][sub c] decreased with decreasing cathodic off-potential (E[sub off]) whenmore »« less
