We present a new approach for filling arbitrary holes in Finite Element (FE) models composed of independent meshes which are commonly used in Computer Aided Engineering (CAE). During the preprocessing of an FE model for fluid structure simulation a closed structure hull is required in order to subsequently generate a volume mesh representing the fluid. Today’s complex CAE models include thousan...

198 Triangles Std. Wire Frame 2 Triangles 32×32 Texture Finite element models used in crash worthiness simulations now contain more than one million mostly quadrilateral elements. Interactive visualization of those models for preand postprocessing applications cannot be achieved by brute force rendering of all triangles on even advanced graphics hardware. Well-known mesh simplification algorith...

controversy exists regarding cavity preparation for restoration of interproximal caries in posterior teeth in terms of preserving the tooth structure and suitable stress distribution. this study aimed to assess the effect of extension and type of class ii cavities and the remaining tooth structure in maxillary premolars restored with composite resin on the biomechanical properties of teeth usin...

Structural damage detection is a field that has attracted a great interest in the scientific community in recent years. Most of these studies use dynamic analysis data of the beams as a diagnostic tool for damage. In this paper, a massless rotational spring was used to represent the cracked sections of beams and the natural frequencies and mode shape were obtained. For calculation of rotational...

Because of the substantial difference in stiffness between matrix and nanotube in CNT composite, the stress transfer between them controls their mechanical properties. This paper investigates the said issue, analytically and numerically, in axial load using representative volume element (RVE). The analytical model was established based on the modified Cox’s shear lag model with the use of some ...
