The main causes of aerodynamic drag for automotive vehicles are the flow separation at rear end vehicles. By reducing force, it is possible to increase fuel economy. Aerodynamic component i.e. Frontal Deflectors (FD) commonly used on trucks prevent separation. themselves do create drag, but they also reduce drags by preventing downstream. aim this paper quantify effect frontal deflectors improv...

Laser Shock Processing (LSP) is an innovative surface treatment technology. LSP can induce compress residual stress layer in the surface of metallic materials, which is used for improving the fatigue life. In this study, the propagation course of typical laser shock wave in material was analyzed according to the theory of plasticity dynamics and the theory of stress wave. The effects of laser s...

The present work is carried out to investigate heat transfer and friction factor characteristics of fluid (air) flow through turbulent channel i.e. parallel plate heat exchanger for different geometry and designs parameters, with a bottom plate applied to uniform constant heat flux thermal boundary condition, and upper plate is provided with a insulated condition. The fluid domain is designed u...

FEA-based simulation has become an integral part of engineering practice. Sophisticated FEA software such as ANSYS are used in industry for the design and analysis of complex engineering systems. However, the use of such software in the undergraduate mechanical engineering curriculum has been limited so that students are not prepared adequately to make appropriate use of these powerful tools. A...

The software mor4ansys that allows engineers employ the modern model reduction technique to the finite element models developed in ANSYS is presented. We focus on how one extracts the required information from ANSYS and makes the model reduction implementation not dependent on a particular sparse solver in C++. We discuss the computational cost and give examples related to structural mechanics ...

one of the main architectural characteristics in the central area of iran is the relation between life and climatic conditions; e.g., the four-seasonal house which is a typical kind of the central-yard house. as the climate of isfahan is more pleasant than other desert regions in the central part of iran, wind towers are replaced with skylights to ventilate the pool area of hoze-khane. so far, ...

After discussing general properties of implicit Finite Element analysis using ANSYS and explicit analysis using LS-DYNA it is shown when and how quasi-static limit load analyses can be performed by a transient analysis using explicit time integration. Then we focus on the remaining benefits of implicit analysis and how a proper combination of ANSYS and LS-DYNA can be used to prepare the transie...
