Over the last few years, Additive Manufacturing, or as it is sometimes known, 3D printing, has become a significant research field for researchers worldwide. The necessity to increase strength of materials and minimize their weight in automotive aviation industries urged engineers scientists conduct more investigations identify manufacturing methods replace classical ones. involves building geo...

This work introduces a new operator-splitting method for solving the two-dimensional (2D) and three-dimensional (3D) parabolic equations. The aim is to reduce the computational complexity without loss of accuracy. Firstly, we split the 2D and 3D parabolic equations into a sequence of one-dimensional (1D) parabolic equations respectively, then we solve each 1D parabolic equation by using finite ...

background: different postdesigns and materials are available; however, no consensus exists regarding superiority for stress distribution. the aim of this study was to evaluate the effect of design and material of post with or without ferrule on stress distribution using finite element analysis. materials and methods: a total of 12 three‑dimensional (3d) axisymmetric models of postretained cent...

distal extension removable partial denture is a prosthesis with lack of distal dental support with a 13-fold difference in resiliency between the mucosa and the periodontal ligament, resulting in leverage during compression forces. it may be potentially destructive to the abutments and the surrounding tissues. the aim of this study was to assess the effect of implant location on stress distribu...

The design of headframe foundation is always a cumbersome and difficult process. Traditionally its design is focused on 2D construction drawings. Currently it need its 3D model and often proceed finite element analysis for its importance. Based on the analysis of its design and model process we find that the core work of 3D modeling for headframe foundation is its vertices calculation. Therefor...
