A finite element methodology has been developed for predicting the behaviour of honeycomb structures. Dynamic analysis of hexagonal aluminium honeycomb structures is carried out using PAM-CRASH, an explicit FE analysis code, and the result are verified against experimental data. Relationship between the crushing behaviour of honeycomb and simulation parameters has been established. The simulati...

Concussion or head impact involves the brain injury from mild to severe. Most of the brain injury mechanism and brain lesions can be investigated from medical imaging. Alternatively, finite element model (FE model) of head impact is used for simulation and analyzing the brain concussion. This paper proposes finite element model of maxilla bone, left and right zygomatic bones impact for further ...

introduction: the resistance to fracture of endodontically treated teeth restored with esthetic post systems has not been extensively researched. this in vitro study compared the fracture patterns of endodontically treated teeth with esthetic post systems with different analysis methods. materials and methods: a total of 26 recently extracted human maxillary central incisors were decoronated an...

The objective of this study is to develop a computational framework for investigating the dynamic behavior and the internal loading conditions of the human foot complex during locomotion. A subject-specific dynamic finite element model in the sagittal plane was constructed based on anatomical structures segmented from medical CT scan images. Three-dimensional gait measurements were conducted to...

The systematic application of uncertainty and reliability analysis to engineering structures of practical interest, requires the availability of powerful and efficient software, both for the FE modeling and for the uncertainty analysis. Ideally this software should seamlessly interface existing finite element codes, in order to harness the state-of-theart in finite element modeling and to facil...

The main objectives of this research task were to conduct an in-depth evaluation of the single-unit truck (SUT) finite element model with respect to its ability to accurately simulate its interaction with roadside safety hardware and to identify areas of possible improvements. The model's primary purpose is to be used as a " bullet " object for computational evaluation of roadside safety hardwa...

a non-linear finite element model could be a useful tool in the development of a method of predicting soil pressure-sinkage behaviour, and can be used to investigate and analyze soil compaction. this study was undertaken to emphasize that the finite element method (fem) is a proper technique to model soil pressure-sinkage behaviour. for this purpose, the finite element method was used to model ...

The preferred method of assessing the risk of an osteoporosis related fracture is currently a measure of bone mineral density (BMD) by dual energy X-ray absorptiometry (DXA). However, other factors contribute to the overall risk of fracture, including anatomical geometry and the spatial distribution of bone. Finite element analysis can be performed in both two and three dimensions, and predicts...

A two-dimensional (2-D) explicit dynamics finite element (FE) model of a rolling element bearing was solved using a commercial FE software package, LS-DYNA. It was found that the modelled bearing vibration signals contain a significant amount of numerical noise. This paper provides an explanation of the physical mechanism by which the numerical noise is generated. The noise frequencies were ana...
