Background Over the past two decades finite element (FE) analysis has become a popular tool for researchers looking to simulate the biomechanics of the foot in people with diabetes. The ultimate aims of these simulations have been to improve understanding of the complicated nature of mechanical loading and to inform interventions designed to prevent plantar ulceration. This review is intended t...

No technology is presently available to provide real-time information on internal deformations and stresses in plantar soft tissues of individuals during evaluation of the gait pattern. Because internal deformations and stresses in the plantar pad are critical factors in foot injuries such as diabetic foot ulceration, this severely limits evaluation of patients. To allow such real-time subject-...

Although Cu and Fe are immiscible under equilibrium conditions, they can form supersaturated solid solutions by mechanical alloying. In this paper, nano-structured of the metastable Cu-Fe phase containing 10, 15, 20 and 25% wt Fe were synthesized by intensive ball milling for 15h, in order to achieve a solid solution of Fe in Cu. The phase composition, dissolution of the Fe atoms into the Cu ma...

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...

Fat Embolism (FE) develops in 90% of all bone fractures. Fat Embolism Syndrome (FES) is a serious manifestation of FE with an incidence of 0.5-2.0% among all long bone fractures. It is believed to be caused by the toxic effects of free fatty acids but still, there is considerable controversy over both the source of fat emboli and their mode of action [1]. The exact pathogenesis is unclear but i...

EXAFS spectra for all K absorption edges and X-ray scattering data have been obtained on an amorphous Fe-Zr sample prepared by mechanical alloying and a rapidly quenched Co-Zr one. Partial pair distribution fnnctions have been determined as a solution of an inverse ill-posed problem for the system of integral equations describing combined experimental data. For Fe-Zr and Ca-Zr amorphous alloys ...

This paper presents an automated deep learning-based design methodology to facilitate the and optimization processes in electro-mechanical energy conversion devices. To validate generality of model, a complex machine structure with hybrid Permanent Magnets (PMs) is selected as case study. First, machine’s geometrical topology respective variables are described cylindrical coordinate system prog...

The white layer formed during the hard-cutting process impacts surface quality and mechanical properties of a workpiece significantly. Obtaining accurate critical cutting speed for formation is beneficial to control parameter selection cutting. Accordingly, combining with finite element (FE) method, model was developed based on solid phase transformation free energy theory, in which thermal–mec...
