We present a construction of a visually smooth surface which interpolates to position values and normal vectors of randomly distributed points on a 3D object. The method is local and uses quartic triangular and bicubic quadrilateral patches without splits. It heavily relies on an edge deleting algorithm which, starting from a given triangulation, derives a suitable combination of threeand four ...
this article deals with the buckling analysis of perfectly bonded cross-ply laminated composite plates reinforced by wavy carbon nanotubes (cnts) under in-plane loads using element free galerkin (efg) method based on first-order shear deformation theory (fsdt). the wavy single-walled cnts and poly-co-vinylene are used for the fibers and the matrix, respectively. the cnt fibers are distributed i...
The need of polygonal elements to represent the domain is gaining interest among structural engineers. The objective is to perform static analysis and topology optimization of a given continuum domain using the rational fraction type shape functions of six node hexagonal elements. In this paper, the main focus is to perform the topology optimization of two-dimensional plate structures using Evo...
nanocomposites made of carbon nanotube (cnt) bundles have attracted researchers’ attention due to their unusual properties such as: light weight, flexibility and stiffness. in this paper, the effects of straight and rope-shaped bundles on nanocomposite effective mechanical properties are investigated. first, fea models are created consisting of cnts with different shapes of straight and rope-...
the the main objective of this research paper is to present 3-d elasticity solution for free vibration analysis of elastically supported continuously graded carbon nanotube-reinforced (cgcntr) annular plates. the volume fractions of oriented, straight single-walled carbon nanotubes (swcnts) are assumed to be graded in the thickness direction. an equivalent continuum model based on the eshelby-m...
This study indicates the analysis of functionally graded carbon nanotube reinforced composite (FG-CNTRC) plates using a four-node quadrilateral element related to C0-type Reddy’s third-order shear deformation theory (C0 HSDT) and cell-based smoothed strains (CS) strategy. is surely taking advantages desirable properties theory. Besides, FG-CNTRC with advanced material are changed from bottom to...
Given an n-sided polygon P on the plane with $$n \ge 4$$ , a quadrangulation of is geometric graph such that boundary outer face and each finite quadrilateral. Clearly, quadrangulatable (i.e., admits quadrangulation) only if n even, but there non-quadrangulatable even-sided polygon. Ramaswami et al. [Comp Geom 9:257–276, (1998)] proved every even at most $$\lfloor \frac{n-2}{4} \rfloor$$ Steine...
