Influence of basalt fiber on mode I and II fracture properties of asphalt mixture at medium and low temperatures

, 2021
Basalt fiber could effectively improve the crack resistance of asphalt mixture. However, most cracks in asphalt pavement present complex fracture characteristics.

Determination of the mixed mode I/II fracture characteristics of heat-treated granite specimens based on the extended finite element method

Engineering Fracture Mechanics, 2021
Previous researches mainly concentrate on investigating the mixed mode I/II fracture characteristics of heat-treated rocks through laboratory tests. This paper makes an effort to obtain the mixed mode fracture characteristics of heat-treated granite by ...

The mixed mode brittle fracture criteria in siliding mode fracture

Applied Mathematics and Mechanics, 1985
It is well-known that the present mixed mode brittle fracture criteria are all the opening mode fracture criterion. We consider that mixed mode brittle fracture of sliding mode fracture exists too. Hence we propose three criteria of mixed mode brittle fracture of sliding mode fracture;: the radial shearing stress criterion, the maximum shearing stress ...

The fourth mode of fracture in fractal fracture mechanics

International Journal of Fracture, 2000
This paper offers a systematic approach for obtaining the order of stress singularity for different self-similar and self-affine fractal cracks. Mode II and Mode III fractal cracks are studied and are shown to introduce the same order of stress singularity as Mode I fractal cracks do. In addition to these three classical modes, a Mode IV is discovered,

Fracture energy of bone in a shear mode

Medical & Biological Engineering, 1974
The role of the osteon as the basic strengthening unit of compact bone is discussed. Using previous work on the shear strength of bone, an analysis is given enabling a computation to be made of the mode-II (debonding) fracture energy. The evidence suggests that bone, like many reinforced composites, derives its excellent fracture characteristics from ...

Fracture Modes in a Binary Titanium Alloy

Materials Characterization, 1972
Abstract The scanning electron microscope has been used to investigate the fracture surfaces of Ti-Cr alloys, and special emphasis has been placed on the effects of the omega phase on the modes of fracture. It has been found that an alloy containing the athermal omega phase exhibits a different mode of fracture from that of an alloy containing the ...

Fracture Modes of Oriented Polypropylene

Journal of Reinforced Plastics and Composites, 1992
This paper describes the fracture modes of both notched and unnotched polypropylene which has been oriented with a solid phase roll-drawing process. The shear strength of the unnotched material is estimated with a single off-axis tensile test. The notched specimens, when stressed in the roll-drawn direction, fractured normal to the

Deformation modes in plasticity and fracture

Crystal Research and Technology, 1984
AbstractThe character of collective motion of the point defects and dislocations of various types determines the mode of plastic deformation and of fracture as its final stage. The concepts of the translational and rotational modes appeared at an early stage in the study of the mechanisms of plastic deformation in crystals and have undergone ...
