This report explores the fundamental concepts of the J-Q description of crack-tip fields, the fracture toughness locus and micromechanics approaches to predict the variability of macroscopic fracture toughness with constraint under elastic-plastic conditions. While these concepts derived from plane-strain considerations, initial applications in fully 3D geometries are very promising. Computational results are presented for a surface cracked plate containing a 6:1 semi-elliptical, a=tl4 flaw subjected to remote uniaxial and biaxial tension. Crack-tip stress fields consistent with the J-Q theory are demonstrated to exit at each location along the crack front. The micromechanics model employs the J-Q description of crack-front stress to interpret fracture toughness values measured on laboratory specimens for fracture assessment of the surface cracked plate. The computational results suggest only a minor effect of the biaxial loading on the crack tip stress fields and, consequently, on the propensity for fracture relative to the uniaxial loading ...

Elastic-Plastic Analysis of Cracks on Bimaterial Interfaces. Part 1. Small Scale Yielding ( Book )
1 edition published in 1987 in English and held by 1 WorldCat member library worldwide
Full field numerical solutions for a crack which lies along the interface of an elastic-plastic medium and rigid substrate are presented. The solutions are obtained using a small strain version of the j2 deformation theory with power law strain hardening. In the present article result for loading causing only small scale yielding and fully plastic behavior will be presented. The oscillatory stresses on the bond line and overlapping of the crack faces, characteristic of small strain linear elasticity, are shown to be essentially precluded by material nonlinearity. In addition we find that, although the near tip fields do not appear to have a separable form as for the well known HRR fields in homogeneous media, they do bear interesting similarities to certain mixed mode HRR fields. Numerical procedures appropriate for solving a general class of interface crack problems are described. A description of a numerical method for extracting the mixed mode stress intensities for cracks at interfaces, and in homogeneous isotropic or anisotropic media, is included

Three-Dimensional Transient Analysis of a Dynamically Loaded Three-Point-Bend Ductile Fracture Specimen ( Book )
1 edition published in 1986 in English and held by 1 WorldCat member library worldwide
A transient three dimensional full field analysis of a three point bend fracture specimen dynamically loaded into the fully yielded plastic state has been carried out. The specimen is rapidly loaded by means of a concentrated transverse force applied at midspan on the uncracked surface of the specimen. The material is ductile and fracture initiation occurs after substantial plastic deformation has developed in the uncracked ligament. Furthermore it is supposed that the crack tip conditions are such that the J integral may be adopted as a characterizing parameter. An expression is derived for the local energy flux appropriate to a three dimensional crack front. Based on this fundamental crack tip flux integral, a domain integral representation for J, suited for the finite element method is obtained. Using the domain integral, accurate pointwise/local values of J along a three dimensional crack front can be extracted from numerically determined field quantities. Transient loading, geometry and plastic deformation on the variation of J along the crack front are examined. The present study determines conditions under which the value of J at initiation may be inferred from quantities that are directly measurable in a dynamic fracture experiment. Earlier a transition time was introduced to provide a practical bound on the time range over which conditions of J dominance prevailed and the deep crack formula was applicable under transient loadings. The transition time concept is further examined. The full field solutions allow comment on the suitability of proposed surface locations for measurement of moment deep crack formula for J, Implications for fracture testing of tough materials at relatively high loading rates are discussed

Mechanics of Multi-Layered Materials and Composites ( )
1 edition published in 1995 in English and held by 1 WorldCat member library worldwide
Using a video microscope equipped with microscope lens, we have recorded various stages of kink band formation and band width broadening in unidirectional fiber composites. These deformation modes are different from the commonly assumed kinematics employed by many investigators. The in-situ video pictures show that the early stage of kink band formation involves progressive, cooperative fiber bending/rotation and plastic shearing of the matrix within a shallow narrow band of about 10 fiber diameters wide. This deformation mode causes geometric softening of the material within the band. At some point in this process, fiber rotation within the kink band is halted. The termination of fiber rotation, referred to as fiber lock-up, is believed to be brought about by the stiffening of the composite shearing response at large shear strains. This forces the kink band to spread into the unkinked material (which is soft in shear) by band width broadening to accommodate the continuous overall end-shortening of the specimen. In the band broadening stage, the bends in the fiber (at the edges of the kink band) propagate into the unkinked material much like a pair of dislocations moving away from one another. Band widths of 30 to 50 fiber diameters with a steeper inclination than the initial band orientation have been observed. The final width of the kink band is set when the fibers snap. The mechanism of band broadening bears some similarity to neck propagation in certain polymers often termed cold drawing

J Integral Estimates for Strain Hardening Materials Using Fully Plastic Solutions ( Book )
1 edition published in 1974 in English and held by 1 WorldCat member library worldwide
General procedures are proposed which use the elastic and the fully plastic solutions to interpolate behavior from the small scale yielding range to the fully plastic range. The relations between the J-integral, load point displacement, crack opening displacement and the applied load thus developed, are applicable to test configurations and cracked bodies in general. To assess the accuracy of the estimated relationships, a detailed numerical investigation, which employs an accurate finite element approach, is carried out for a particular configuration under anti-plane shear. The results obtained from the full numerical calculations, for values of the applied load well into the fully plastic range, are in excellent agreement with the estimated results

Computational and Experimental Investigation of Elastic-Plastic Fracture under Dynamic Conditions ( )
1 edition published in 1986 in English and held by 1 WorldCat member library worldwide
Our studies on dynamic fracture have led to the concept of a transition time. The response of a ductile fracture specimen can be characterized by a short-time response dominated by discrete waves, an intermediate-time response dominated by the structural inertia and kinetic energy and a long-time response dominated by deformation energy (or stress work) . The transition time, tT, is defined as the time beyond which the total deformation energy exceeds the total kinetic energy of the specimen. Using dimensional and elementary model analyses, we have obtained a simple formula for the transition time. The formula has been verified by two-dimensional and three- dimensional full-field finite element analysis of a dynamically loaded three- point-bend ductile fracture specimen. While the transition time can serve to distinguish the short-time from the long-time response, it has an additional role in nonlinear fracture mechanics which is discussed in the next paragraph
