Extracting fracture mechanics parameters (higher-order coefficients of Williams series expansion) from FEM analysis and digital photoelasticity method

Fracture of Femur: Simulation and Photoelasticity Analysis

Bones, particularly long ones, are among the most fascinating and intriguing materials, not only because of the complicated structure, but also because of their mechanical behavior, which is still not completely understood.Finite Element computer simulations of the modal behaviour of human femur were compared to experimental results of the resonance frequencies of actual bones, indicating that ...

Fracture Mechanics Analysis of Fourth Lumbar Vertebra in Method of Finite Element Analysis

Objective: In this paper, finite element model of the L4 vertebra subjected to combination of compression and flexion loading in isotropic and anisotropic cases is investigated. Methods: In both cases, the vertebra is considered homogeneous. Also, the body of vertebra is divided to cancellous and cortical sections in anisotropic model, but the process is assumed isotropic such as isotropic mode...

Higher Order Weight Functions in Fracture Mechanics of Multimaterials

Extracting Higher Order Relations From Biomedical Text

Argumentation in a scientific article is composed of unexpressed and explicit statements of old and new knowledge combined into a logically coherent textual argument. Discourse relations, linguistic coherence relations that connect discourse segments, help to communicate an argument’s logical steps. A biomedical relation exhibits a relationship between biomedical entities. In this paper, we are...
