1. Simulation of Mode I Strain Energy Release Rate for Rectangular Laminated Composite Plate Using a Simple Finite Element Model

Mahmoud Mehrdad Shokrieh; Mohsen Ghajar

Volume 3, Issue 4 , September 2010

Abstract
  In this paper the critical strain energy release rate for T300/913 carbon-epoxy laminated composites has been studied using ANSYS finite element software based on virtual crack closure technique (VCCT). Compact Tension (CT) specimen has been used for numerical analyses and the geometrical dimensions ...  Read More

2. Exergy Analysis and Optimization of Combined Rankin Power and Ejector Refrigeration Cycle

MohamadMehdi Rashidi; Payman Lashgari

Volume 3, Issue 4 , September 2010

Abstract
  In this paper, a new combined power and refrigeration cycle is proposed, which combines the Rankin power cycle and the Ejector refrigeration cycle. This combined cycle produces both power output and refrigeration output simultaneously. This cycle is driven by the flue gas of gas turbines, industrial ...  Read More

3. Effect of Methanol Concentration and Channel Depth on Performance of Direct Methanol Fuel Cell

Ebrahim Alizadeh; Kourosh Sedighi; Mousa Farhadi; Mohsen Shakeri

Volume 3, Issue 4 , September 2010

Abstract
  Effect of methanol concentration and channel depth of bipolar plates on the performance of single direct methanol fuel cell was investigated experimentally. The membrane used in this experiment was Nafion117. Dimension of the single cell were 10cm 10 cm. Methanol concentrations of 0.50, 1.0, 1.5, 2.0, ...  Read More

4. Heat Transfer Characteristics and Optimization of a Porous Radiant Air Heater, Using DOM, under the Influence of 2-D Rectangular Radiative Field

MohamadMehdi Keshtkar; AbdoReza Ganjalian Nasab

Volume 3, Issue 4 , September 2010

Abstract
  This work presents the heat transfer characteristics of a new type of porous radiant air heater that operates on the basis of effective energy conversion method between flowing gas enthalpy and thermal radiation. At each layer, the gas and solid phases are considered in non-local thermal equilibrium, ...  Read More

5. Investigation of Drawing Ratio Effect on Chart Rupture in Hydroforming Process

MohamadAmin Bahari; Rouzbeh Alipour

Volume 3, Issue 4 , September 2010

Abstract
  Hydroforming process in one of the most effective production method, for improving the drawing ratio in sheet metal forming process. This is due to the fact that in hydroforming process, forming takes place using a punch which drives the part forward via a controlled fluid pressure. In this paper, deep ...  Read More

6. Culling Force Investigation in Turning Process via Ultrasonic Assisted Turning on Al7075 Workpiece

Saeed Amini; MohamadJavad Nategh; Amir Abdollah

Volume 3, Issue 4 , September 2010

Abstract
  In this paper, Ultrasonic assisted cutting (UAT) process has been investigated. The cutting technique is among the advanced machining techniques which improve cutting capability of materials. Vibratory tool is made under longitudinal mode with 10 micron amplitude and 20 KHz frequency, in such a way that ...  Read More

7. Numerical Study on Propagation of Flame in Laminar Pre-Mixed Combustion

Ali Lohrasbi

Volume 3, Issue 4 , September 2010

Abstract
  Premixed combustion is widely used for reducing pollutant emission from combustion chambers. However, these systems may be sensitive to complex phenomena such as flashback. In the present study flame, flashback and structure of premixed laminar flames are investigated theoretically. The mathematical ...  Read More

8. Finite Element Simulation of C.V. Joint Forging of Prid Using Arbitrary Lagrangian-Eulerian Method

MohamadReza Seydi; Mohsen Lohmousavi

Volume 3, Issue 4 , September 2010

Abstract
  One of the most important parts of power transmission in automotives is C.V. joint, which consists of four components where exterior bowl is one of them. Due to its complexity, and importance in automobile and existence of high stresses, forging process is the only cost effective method of production. ...  Read More
