Unified Tensile Fracture Criterion

Physical Review Letters, 2005
We find that the classical failure criteria, i.e., maximum normal stress criterion, Tresca criterion, Mohr-Coulomb criterion, and von Mises criterion, cannot satisfactorily explain the tensile fracture behavior of the bulk metallic glass (BMG) materials.

Fracture Criterion for Fracture Mechanics of Magnets

Chinese Physics Letters, 2003
The applicability and limitation of some fracture criteria in the fracture mechanics of magnets are studied. It is shown that the magnetic field intensity factor can be used as a fracture criterion when the crack in a magnet is only affected by a magnetic field.

A fabric-dependent fracture criterion for bone

Journal of Biomechanics, 1999
A fracture criterion for bone tissue is proposed. Bone material is considered to be anisotropic and its properties are described by invoking the concept of directional variation of porosity. The fracture criterion is expressed as a scalar-valued function of the stress tensor and it incorporates an orientation-dependent distribution of compressive ...

An experimental criterion of fracture. The Det.-criterion

Soviet Materials Science, 1993
From this study is concluded that for various crack problems, the Det.-criterion of fracture gives theoretical results which are agreed with the experimental results. The interest in this study is that the distribution of the determinant of the stress tensor is calculated experimentally from isochromatic- and isopachic-fringe patterns and so, the ...

The criterion of fracture

Polymer Engineering & Science, 1964
AbstractDupre's theory that work of rupture equals increase in surface energy, and Griffith's hypothesis (based upon Dupre's that a crack propagates when strain energy decrease equals or exceeds work required to creat two new surfaces are shown to be incorrect.

A Fracture toughness criterion for concrete

Engineering Fracture Mechanics, 1985
Abstract Many have attempted to calculate the fracture toughness of concrete in Mode I by testing notched beam specimens. It has been observed that when K I c is calculated from the measured values of the maximum load, the initial notch length and using the formulas developed from LEFM, its value is dependent on the dimensions of the ...
