This study provides an insight in the analytical estimation of electric field along surface a stress grading system (SGS) end-winding region electrical machine. An approach is derived for materials (FGMs) having power-law electric-field-dependent conductivity. Despite some limitations, introduced model can be used preliminary analysis SGS with specific geometric and dielectric parameters, both ...

In this paper, the steady-state and transient heat transfer processes of functionally graded materials (FGMs) are analyzed using a coupled thermo-mechanical model in GPU parallel multiphysics finite–discrete element software, namely MultiFracS. First, to handle problem heterogeneous is verified. Then, advantages disadvantages FGMs composite response thermal shock loads compared results indicate...

Equations governing the flow of fluid containing visco-hyperelastic particles are developed in an Eulerian framework. The novel feature introduced here is to write an evolution equation for the strain. It is envisioned that this will simplify numerical codes which typically compute the strain on Lagrangian meshes moving through Eulerian meshes. Existence results for the flow of linear visco-hyp...

In the present article, the thermal analysis of the cylinder and the piston in four-cylinder engines, made of functionally graded materials (FGMs), has been performed by using the super element method. The objective of using FGMs in the cylinder and the piston is to increase their performance. FGMs include a combination of ceramics and metals. Inside the cylinder, the ceramic is considered and ...

The aim of this work is to develop a new hyperelastic and anisotropic material mimicking histological and mechanical features of healthy and aneurysmal arterial tissues. The target material is constituted by rhombic periodic lattices of hyperelastic fibres embedded into a soft elastomer membrane. Based on a previous theoretical work yielding to an optimized microstructural arrangement and mecha...

The first publication of the work [1] did not present one of the authors' names. Kunalan Ganthel has now been added to the author list. In addition, Habib Sherkat has been added to the Acknowledgements, with thanks for providing help with the use of hyperelastic module of Abaqus Software. Prospects of implant with locking plate in fixation of subtrochanteric fracture: experimental demonstration...

The elastic as well as time-dependent mechanical response of the vocal fold cover (epithelium and superficial layer of the lamina propria) under tension is one key variable in regulating the fundamental frequency. This study examines the hyperelastic and time-dependent tensile deformation behavior of a group of human vocal fold cover specimens (six male and five female). The primary goal is to ...

A. Samani, I. Sack, D. Plewes University of Toronto, Sunnybrook and Women's College Health Sciences Centre, Toronto, Ontario, Canada Synopsis To increase the displacement SNR in breast MR elastography, tissues are compressed significantly. As a result, breast tissues undergo large deformations. This leads to significant geometric and material nonlinearities. In this study, methods for treating ...
