Morphology of two dimensional fracture surface [PDF]

Journal of Statistical Mechanics: Theory and Experiment, 2006
We consider the morphology of two dimensional cracks observed in experimental results obtained from paper samples and compare these results with the numerical simulations of the random fuse model (RFM).

Statistical Physics of Fracture Surfaces Morphology [PDF]

Journal of Statistical Physics, 2005
Experiments on fracture surface morphologies offer increasing amounts of data that can be analyzed using methods of statistical physics. One finds scaling exponents associated with correlation and structure functions, indicating a rich phenomenology of ...

Experimentally induced incomplete burst fractures - a novel technique for calf and human specimens

BMC Musculoskeletal Disorders, 2012
Background Fracture morphology is crucial for the clinical decision-making process preceding spinal fracture treatment. The presented experimental approach was designed in order to ensure reproducibility of induced fracture morphology.

Relationship Between Carpal Bone Morphology and Distal Radius Fracture Pattern

Journal of Contemporary Medicine, 2022
Background: In this study, we examined whether carpal bones (lunate, hamate, capitate) morphologies and fourth metecarp-capitate articulation have an effect on the distal radius fracture pattern.

A micromechanical fracture analysis to investigate the effect of healing particles on the overall mechanical response of a self-healing particulate composite [PDF]

, 2019
A computational fracture analysis is conducted on a self‐healing particulate composite employing a finite element model of an actual microstructure. The key objective is to quantify the effects of the actual morphology and the fracture properties of the ...

Fracture Behavior of Single-Crystal Sapphire in Different Crystal Orientations

Crystals, 2021
In order to study the anisotropy of fracture toughness and fracture mechanism of single-crystal sapphire, the three-point bending tests and the single-edge V-notch beam (SEVNB) were used to test the fracture toughness of A-plane, C-plane, and M-plane ...

Simulation of Fracture Morphology during Sequential Fracturing

Processes, 2022
During hydraulic fracturing, the aperture of hydraulic fractures will shrink by the in-situ stress, but will not fully close because of the existence of proppant inside the fracture. In previous studies, few people noticed the existence of proppant, which has resulted in the inaccuracy of simulation results. In this study, based on the boundary element
