Local criteria for ductile fracture

International Journal of Fracture Mechanics, 1968
Strain distributions in specimens suitable for studying the initiation of fracture are reviewed, and distributions are developed for the steady-state propagation of cracks in plane strain lension of fully plastic materials. The functional forms of local fracture criteria are discussed for different metallurgical mechanisms. It is concluded that: a)

Criteria for ductile fracture and their applications

Journal of Mechanical Working Technology, 1980
Abstract Criteria for ductile fracture of pore-free materials and porous materials are described. A method of estimating material constants in these criteria is also given. Applications of the criteria to prediction of the fracture strain in several types of metal working processes for pore-free materials and porous materials are described.

Fracture Criteria for Piezoelectric Ceramics

Journal of the American Ceramic Society, 1995
Fracture criteria for piezoelectric materials were investigated. Mode I and mixed mode fracture tests were performed on PZT‐4 piezoelectric ceramics to verify the validity of the mechanical strain energy release rate as a fracture criterion. Experimental results indicated that crack extension could be aided or impeded by an electric field, depending on

Criteria of nonlinear fracture mechanics

Strength of Materials, 1988
Difficulties are experienced in using some of the examined fracture criteria in the elastoplastic region. The apparent fracture toughness varies in a wide range. The effect of the thickness of the specimen on cracking resistance is relatively small.

Criteria for nearly brittle fracture

International Journal of Fracture Mechanics, 1968
Nearly brittle fracture of solids, that is, brittle fracture without appreciable plastic deformation has been divided into two types. One is low stress fracture in. nearly elastic large structures, which occurs before general yielding. The other is brittle fracture of small laboratory specimens below the ductility transition temperature, which occurs ...

Interface Fracture: Failure Criteria

Journal of Applied Mechanics, 2020
Abstract Failure criteria for a crack between two dissimilar materials are presented. Test data from three different material pairs are considered. The first two consist of an interface crack between glass and epoxy and two dissimilar ceramic clays.

Variations on the theme of fracture criteria

Engineering Fracture Mechanics, 1989
Abstract The rate of introduction of new or quasi-new criteria of fracture is steadily increasing with time. However, the possibilities of combining sound physical principles together with simple notions of realistic concepts in mechanics, in conformity with the existing experimental evidence, are rapidly exhausted.
