The finite element (FE) mesh sizing has great influence on computational time, memory usage, and accuracy of FE analysis. Based on a systematic in-depth study of the geometric complexity of a set of connected surfaces, a computational procedure for the generation of FE mesh sizing function is proposed. The computational procedure has three main steps: (1) Generation of source points that determ...

A new technique which allows the simulation of thin ferrite absorbing tiles in a coarse TLM mesh is described. Results are presented which show a good fit to manufacturers' reflectivity curves. Experimental and simulation results for a screened room partially lined with ferrite are presented to demonstrate the accuracy of the method. INTRODUCTION The Transmission Line Matrix (TLM) method of num...

stress-intensity factors (sifs) are the most important parameters in fracture mechanics analysis of structures. these parameters are evaluated for a stationary crack in functionally graded plates of arbitrary geometry using a novel galerkin based mesh-free method. the method involves an element-free galerkin method (efgm), where the material properties are smooth functions of spatial coordinate...

Owing to its fundamental nature, convection-diffusion flows are researched in a number of engineering, scientific, and aeronautical applications. The right meshing approaches necessary for simulations. Major meshes computational fluid dynamics that used find the solutions discretized governing equations include uniform, piecewise-uniform, graded, hybrid meshes. Unintentionally applying might le...

The main aim of this paper is to investigate bending behavior in sandwich plates with functionally graded carbon nanotube reinforced composite (FG-CNTRC) face sheets with considering the effects of carbon nanotube (CNT) aggregation. The sandwich plates are assumed resting on Winkler-Pasternak elastic foundation and a mesh-free method based on first order shear deformation theory (FSDT) is devel...

The recent advancement of solid freeform fabrication, design techniques and fundamental understanding of material properties in functionally graded materials has made it possible to design and fabricate multifunctional heterogeneous objects. In this paper, we present an integrated design and analysis approach for heterogeneous object realization, which employs a unified design and analysis mode...

In this study, static and free vibration analyses of functionally graded (FG) nanocomposite plates, reinforced by wavy single-walled carbon nanotubes (SWCNTs) resting on a Pasternak elastic foundation, were investigated based on a mesh-free method and modified first-order shear deformation theory (FSDT). Three linear types of FG nanocomposite plate distributions and a uniform distribution of wa...
