The behaviour of microcracks in compact bone
European Journal of Morphology, 2005This paper summarises four separate studies carried out by our group over the past number of years in the area of bone microdamage. The first study investigated the manner by which microcracks accumulate and interact with bone microstructure during fatigue testing of compact bone specimens.

Calcified Tissue International, 2018
Osteophytes have been suggested to influence the bone mechanical properties. The aim of this study was to compare the microcrack density in osteophytes with that in the other parts of the osteoarthritic femoral neck (FN). The presence of microcracks was investigated in the ultra-distal FN and in the osteophytes in samples obtained during hip ...

International Journal of Engineering Science, 1994
Abstract In the general framework of the thermodynamics of continuous media (TCM) an elastic damageable model with a microcrack opening-closing threshold is proposed to describe the nonlinear constitutive behavior of ceramic-matrix composite. The assumptions currently made (based on physical considerations) are in fact a direct consequence of the ...

The effects of internal, microscopic defects or discontinuities on the macroscopic behavior of materials is an important study in itself. Although materials scientists have long worked on the effects of dislocations in metals, crystal defects in ceramics, and internal cracking in glass, it has only been relatively recently that attention has been given

Mechanics Research Communications, 1986
A series of basic concepts are introduced. The method to discretize the damage mechanism is founded. Damage evolution equations are given that reflect the crack growth law. Finally, the theory is used in an example of uniaxial stress state and the stress jump down phenomena is shown.

Microcracks in the Earth's crust
First Break, 1985The presence or absence of cracks within in situ crustal rocks is open to wide misunderstandings because of the inaccessibility of the material and the difficulty of reproducing in situ conditions in the laboratory. There is now evidence from a wide range of results that most crustal rocks are pervaded by aligned liquid-filled microcracks, where the ...

Microcracking in Polycrystalline Solids
Journal of Engineering Materials and Technology, 1988A polycrystalline brittle solid may undergo grain boundary micro-cracking due to residual stresses or applied load. This paper contains some results pertaining to the loss of macroscopic stiffness of such solids when all micro-cracks are open and when some may be closed and be subject to frictional sliding.

Microcracks in chromium electrodeposits
Journal of Materials Science, 1997The internal stress in chromium deposits plated using a sulphate catalyst was determined using a bent cathode method. Chromium deposits exhibited a high internal tensile stress which decreased with increasing deposit thickness. Surface structures and microcrack patterns were studied using secondary electron and y-modulation techniques and atomic force ...

A microcrack model of rock inelasticity part II: Propagation of microcracks
Mechanics of Materials, 1982Abstract The second stage of inelasticity—kinking and propagation of secondary (dilatant) microcracks—is considered in the framework of the model introduced in Part I (Kachanov, this issue). Three-dimensional problem of branched penny-shaped crack is treated as a set of two-dimensional cross-sections.
