ObjectiveThe American Association for Geriatric Psychiatry (AAGP) Scholars Program was developed to recruit trainees into geriatric psychiatry fellowships and is considered a pipeline fellowship recruitment. Nonetheless, the number of entering declining, making it important identify modifiable factors that may influence trainees’ decisions pursue fellowship. We analyzed survey data from partici...

This work develops RVE-based finite element (FE) models to understand how the microstructure of Ultra-High-Molecular-Weight Polyethylene (UHMWPE) composites affects overall mechanical behaviour laminate. The represent a [0/90] configuration with random fibre packing sequence through thickness each ply, as well variation in cross-sectional shape fibres, both obtained from laminate cross section ...

This paper presents the development of a Representative Volume Element (RVE) for Ultra-high-Molecular-Weight-Polyethylene (UHMWPE) composites. The numerical models were based on fibrillar nature UHMWPE fibres, which consist smaller scale, continuous through-the-length macro-fibrils. A three-dimensional constitutive model macro-fibrils was developed and implemented in LS-DYNA explicit finite ele...

This work focuses on the effects of inclusion proximity elastic behavior dilute matrix-inclusion composites. Rigid or soft monodisperse spherical inclusions are considered with moderate volume fractions. To conduct this study, Representative Volume Elements (RVE) an effective local minimum distance between varying sphere’s radius and one-tenth built. Numerical finite element calculations RVE pe...

Prediction of mechanical properties of carbon nanotube-based composite is one of the important issues which should be addressed reasonably. A proper modeling approach is a multi-scale technique starting from nano scale and lasting to macro scale passing in-between scales of micro and meso. The main goal of this research is to develop a multi-scale modeling approach to extract mechanical propert...

The expansion device is the critical component of micro-to-small scale organic Rankine cycle (ORC) systems, substantially affecting system efficiency and cost. Low isentropic lubrication requirements are main issues associated with using volumetric expanders in ORC systems. Despite contributing to reducing internal leakages an expander, it may compromise performance by adversely evaporator’s th...

In this paper, an adaptive boundary element method (BEM) is presented for solving 3-D elasticity problems. The numerical scheme is accelerated by the new version of fast multipole method (FMM) and parallelized on distributed memory architectures. The resulting solver is applied to the study of representative volume element (RVE) for short fiberreinforced composites with complex inclusion geomet...

A general framework for the multi-scale topology optimisation (TO) of lattice structures (LSs) is presented in this work. The proposed method involves: Non-Uniform Rational Basis Spline (NURBS) hyper-surfaces to represent pseudo-density field describing LS representative volume element (RVE) topology, Solid Isotropic Material with Penalisation (SIMP) approach and strain energy-based homogenisat...

Textile composites describe a broad range of polymer composite materials with textile reinforcements, from woven and non-crimp commodity fabrics to three dimensional textiles. In a general manner textile composites are based on textile preforms manufactured by some textile processing technique and on some resin infiltration and consolidation technique. Due to the complex three-dimensional struc...
