1. Study on tool wear and surface roughness in end milling of particulate aluminum metal matrix composite: Application of response surface methodology

R. Arokiadass*; K. Palaniradja; N. Alagumoorthi

Volume 2, Issue 1 , Summer and Autumn 2012, Pages 1-13

http://dx.doi.org/10.22061/jcarme.2012.35

Abstract
  Metal matrix composites have been widely used in industries, especially aerospace industries, due to their excellent engineering properties. However, it is difficult to machine them because of the hardness and abrasive nature of reinforcement elements like silicon carbide particles (SiCp).In the present ...  Read More

2. Effect of shell axial deformation on flutter of cantilevered cylindrical shells under follower forces

Mohammad Ebrahim Torki Harchegani; Mohammad Taghi Kazemi

Volume 2, Issue 1 , Summer and Autumn 2012, Pages 15-24

http://dx.doi.org/10.22061/jcarme.2012.38

Abstract
  Axial vibration effect of shell particles on dynamic stability of a cantilevered cylindrical shell under an axial follower force was addressed. In spite of free-ended shells, the reduced axial force under this effect cannot be derived analytically. Instead, an approximate method was proposed based on ...  Read More

3. A new positive definite semi-discrete mixed finite element solution for parabolic equations

Zuliang Lu*

Volume 2, Issue 1 , Summer and Autumn 2012, Pages 25-30

http://dx.doi.org/10.22061/jcarme.2012.40

Abstract
  In this paper, a positive definite semi-discrete mixed finite element method was presented for two-dimensional parabolic equations. In the new positive definite systems, the gradient equation and flux equations were separated from their scalar unknown equations.  Also, the existence and uniqueness ...  Read More

4. A numerical and experimental study on tubular channel angular pressing (TCAP) as a noble SPD method

Ghader Faraji*; Mahmoud Mosavi Mashhadi; Karen Abrinia

Volume 2, Issue 1 , Summer and Autumn 2012, Pages 31-36

http://dx.doi.org/10.22061/jcarme.2012.41

Abstract
  The current study conducted a finite element (FE) and experimental investigation on tubular channel angular pressing as a noble severe plastic deformation technique for producing ultrafine grained and nanostructure tubular components. To examine the effects of the TCAP process on the strain distribution ...  Read More

5. Comparing thermal enhancement of Ag-water and SiO2-water nanofluids over an isothermal stretching sheet with suction or injection

Aminreza Noghrehabadi; Mohammad Ghalambaz; Mehdi Ghalambaz; Afshin Ghanbarzadeh

Volume 2, Issue 1 , Summer and Autumn 2012, Pages 37-49

http://dx.doi.org/10.22061/jcarme.2012.43

Abstract
  In the present paper, the flow and heat transfer of two types of nanofluids, namely, silver-water and silicon dioxide-water, were theoretically analyzed over an isothermal continues stretching sheet. To this purpose, the governing partial differential equations were converted to a set of nonlinear differential ...  Read More

6. Applying evolutionary optimization on the airfoil design

Abolfazl Khalkhali*; Hamed Safikhani

Volume 2, Issue 1 , Summer and Autumn 2012, Pages 51-62

http://dx.doi.org/10.22061/jcarme.2012.46

Abstract
  In this paper, lift and drag coefficients were numerically investigated using NUMECA software in a set of 4-digit NACA airfoils. Two metamodels based on the evolved group method of data handling (GMDH) type neural networks were then obtained for modeling both lift coefficient (CL) and drag coefficient ...  Read More

7. Production method of rubber and sulfur FG composites

S. Mohammadi*; F. Abdi

Volume 2, Issue 1 , Summer and Autumn 2012, Pages 63-69

http://dx.doi.org/10.22061/jcarme.2012.47

Abstract
  In the presented work, sulfur concrete and rubber were used for producing functionally graded materials (FGM). The physical and mechanical properties of sulfur concrete and rubber were changed continuously across the thickness. On one side, there was just rubber and, on the other, there was pure sulfur; ...  Read More
