In this paper, the plastic limit load of cylindrical shells with opening subject to combined bending moment and axial force are found by finite element method using ANSYS suite of program. The effect of various parameters such as the geometrical ratios of shell and the shape, size, axial and angular position of the opening on the limit load of cylindrical shells under various loading conditions...

Transmission of high power at high voltages over very long distances has become very imperative. At present, throughout the globe, this task performed by overhead transmission lines. The dual task of mechanically supporting and electrically isolating the live phase conductors from the support tower is performed by insulators. The electrical potential, field and temperature distribution along th...

The paper presents numerical modeling of the dynamics of recently developed electromagnetic valve actuator. The decoupled modelling approach is employed consisting of three-dimensional finite element analysis of the magnetic field of the actuator and solution of the dynamics equations on the basis of functions obtained from the magnetic field analysis. For the finite element analysis ANSYS prog...

The objective of the present paper is to illustrate the use of the commercially available mathematical package MAPLE and other computer software for educational purposes. The problem chosen to illustrate the use of the software is the problem of forced vibrations of an elastic plate. The presentation of the topic is made in a simple manner to make it suitable for introductory graduate or underg...

In this paper, the buckling behavior of a composite lattice cylindrical shell is studied and effects of rib defects on the distribution of stress field and buckling response of the shell is investigated. A three dimensional finite element buckling analysis of the lattice shell is carried out using ANSYS suit of program. Geometrical data and material properties of the shell are obtained from the...

Analysis of seepage and stability is considered as an important case in designing which today, withadvanced numeric software acceptable results will be obtained before and after Construction. In thepresent study, the behavior of earth dam against effective factors was investigated by softwareAnsys12. The studied dam is Maroun soil dam, which is located in 19Km north of Behbehan andconstructed o...

Numerically challenging, comprehensive benchmark cases are of great importance for researchers in the field of CFD. Numerical benchmark cases offer researchers frameworks to quantitatively explore limits of the computational tools and to validate them. Therefore, we focus on simulation of numerically challenging benchmark tests, laminar and transient 3D flows around a cylinder, and aim to estab...

background and aims. there are many edentulous people with severely resorbed residual ridges and non-resilient lining mucosa that are unable to tolerate occlusal forces during functional and parafunctional movements. lining the tissue surface of dentures with a flexible material can theoretically distribute and absorb forces with cushioning effect. the aim of this study was to evaluate the effe...

A signal mass piezoelectric six-degrees-of-freedom (six-DOF) accelerometer is put forward in response to the need for health monitoring of the dynamic vibration characteristics of high grade digitally controlled machine tools. The operating principle of the piezoelectric six-degrees-of-freedom accelerometer is analyzed, and its structure model is constructed. The numerical simulation model (fin...
