OBJECTIVE A three-dimensional (3D) finite element analysis (FEA) on the stress distribution of endodontically treated teeth with titanium alloy post and carbon fiber post with different alveolar bone height. MATERIALS AND METHODS The 3D model was fabricated using software to represent an endodontically treated mandibular second premolar with post and restored with a full ceramic crown restora...

In this paper, symmetric water entry of twin wedges is investigated for deadrise angle of 30 degree. Three numerical simulation of a symmetric impact, considering rigid body dynamic equations of motion in two-phase flow is presented. The two-phase flow around the wedges is solved by Finite Element based on Finite Volume method (FEM-FVM) which is used in conjunction with Volume of Fluid (VOF) sc...

The article considers mainelements of cast-in-placereinforced concrete structures: slabs, beams and columns.Theirbehavior under temperature conditionsof a standard fire has been studied. As an example structures the International Medical Center in Moscow, Western District, territory Innovation "Skolkovo"were considered. software Ansys Workbenchwas usedfor calculation structures. According to re...

This work presents an analysis about microreactors of different geometries for the biodiesel synthesis. The microreactors were made by a polymeric substrate with the photolithography technique. Simulations were made using the computational fluid dynamics software ANSYS-CFX. They show the flow behavior through the microchannels. Experiments were performed to produce biodiesel, with syringe pumps...

The aim of the present paper is to analyze several port configurations in the FairbanksMorse 38D8-1/8 marine diesel engine. The motivation comes from the high number of intake and exhaust ports which characterizes this engine. The scavenging and trapping efficiency were studied by modifying several parameters related to the ports, such as the inclination, shape, pressure and number. To this end...

A fixture is designed and built to hold, support and locate every component to ensure that each is drilled or machined with accuracy and manufactured individually. A fixture can be designed for a particular job. A brake spider includes a spider body with a central opening and a slot for receiving a camshaft and bracket assembly. The brake spider is attached to axle housing via the central openi...

This study aimed to evaluate the influence of loading on a maxillary central incisor with the periodontal ligament (PDL) represented by 2D elastic beam elements using a 2D finite element analysis. Two models (M) were built varying the PDL representation: Mh (homogeneous PDL) and Mht (heterogeneous PDL with beam3 elements). Stress and displacements were determined for three loading conditions (L...

This study based on free vibration analysis and study the behavior of framed structure under different frequency of vibration using ANSYS software and shaking table. A small scale uni-axial shaking table was prepared in laboratory, which can produce lower to moderate vibration, regarding frequency and velocity. Moment resisting framed structures constructed with connecting beam and column eleme...
