Finite Element Analysis of Liver Tissue Modeled Using Micro-CT
One important question for less invasive surgical techniques, such as laparoscopy, is the behavior of the tissue of interest. Non-destructive approaches to determine material properties are of particular benefit. This paper considers the material properties of lamb liver via spherical indentation and finite element analysis. The indentation is performed under a series of step loads with a non c...
متن کاملEfficient 3D finite element analysis of dental restorative procedures using micro-CT data.
OBJECTIVES This investigation describes a rapid method for the generation of finite element models of dental structures and restorations. METHODS An intact mandibular molar was digitized with a micro-CT scanner. Surface contours of enamel and dentin were fitted following tooth segmentation based on pixel density using an interactive medical image control system. Stereolithography (STL) files ...
متن کامل3D Finite Element Meshing from Imaging Data.
This paper describes an algorithm to extract adaptive and quality 3D meshes directly from volumetric imaging data. The extracted tetrahedral and hexahedral meshes are extensively used in the Finite Element Method (FEM). A top-down octree subdivision coupled with the dual contouring method is used to rapidly extract adaptive 3D finite element meshes with correct topology from volumetric imaging ...
متن کاملEvaluation of Disc Cutter Performance in Rock Cutting Process Using 3D Finite Element Method
Today, numerical simulation can be used as a suitable tool to measure large quantities that are very expensive and, in some cases, impossible to measure. One of the important issues in predicting rock mass boreability in excavation with full face tunnel boring machines is estimating the discchr('39')s forces for rock cutting. For this purpose, the linear cutting test is employed. However, limi...
متن کاملAnterior Teeth Splinting After Orthodontic Treatment: 3D Analysis Using Finite Element Method
OBJECTIVE Retention after orthodontic treatment is still an important part of the treatment. Splints are considered as an alternative for removable retainers. The main goal of this study was to assess splinting biomechanically. MATERIALS AND METHODS Three dimensional finite element models (3D) were designed of a mandibular anterior segment which included six anterior teeth with their supporti...
