Comparative Study of various Commercially Available Programs in Slope Stability and Simulation of Dynamic Loading
Abstract: Analysis of slope stability is carried out to identify the most critical failure plane so as to minimize the occurrence of slope failures and landslides. It is always needed to give serious consideration before any construction or development is executed to ensure that the designed slopes remain stable. Slope failure can be determined through appropriate measurement of slope stability. In this study C-programming and GEO4 and Plaxis 2D software have …

Analysis and Modeling of Acoustic Noise in the Switched Reluctance Motors with Finite Element Method
Abstract: Due to high importance of noise in switched reluctance motor (SRM), a coupled electromagnetic-structure simulation model is created for this motor using ANSYS finite element (FE) package. Since the main reason for producing noise and vibration in the SRM is the radial force applied to the stator pole, the radial force waveform is predicted using the 2D FE transient analysis in the developed electromagnetic model. Determination of the frequency modes …

FAILURE ANALYSES OF 16MM THICK SA 516 GR 70 AUTO CLAVE
Abstract: With the acceleration of global industrialization, there is a demand for high- or low-pressure storage of liquids or gases. Because of the complicated operating conditions that will inevitably encounter a possible hazard, pressure vessel design is a critical responsibility. Previous failure studies have revealed that the presence of local loads and discontinuities increases pressure vessel fracture. As a result, a detailed examination of pressure vessel steel from the standpoint of …
