1. Heat generation and radiation effects on steady MHD free convection flow of micropolar fluid past a moving surface

M. Gnaneswara Reddy

Volume 2, Issue 2 , Winter and Spring 2013, Pages 1-10

Abstract
  This paper was concerned with studying the magnetohydrodynamic steady laminar free convection flow of a micropolar fluid past a continuously moving surface in the presence of heat generation and thermal radiation. Similarity transformation was employed to transform the governing partial differential ...  Read More

3. Generalized solution of functionally graded hollow cylinder under torsional load

Y. Bayat; M. Alizadeh; A. Bayat

Volume 2, Issue 2 , Winter and Spring 2013, Pages 23-32

Abstract
  In this paper, a general solution for torsion of hollow cylinders made of functionally graded materials (FGM) was investigated. The problem was formulated in terms of Prandtl’s stress and, in general, the shear stress and angle of twist were derived. Variations in the material properties such as ...  Read More

6. Construction of solitary solution and compacton-like solution by the variational iteration method using He's polynomials

M. Matinfar; M. Ghasemi

Volume 2, Issue 2 , Winter and Spring 2013, Pages 59-68

Abstract
  Variational Iteration method using He's polynomials can be used to construct solitary solution and  compacton-like solution for nonlinear dispersive equatioons. The chosen initial solution can be determined in compacton-like form or in solitary form with some compacton-like or solitary forms with ...  Read More

7. Finite element comparison of single, bi-layered and three-layered tube hydroforming processes

Gh. Payganeh; J. Shahbazi Karami; K. Malekzadeh Fard

Volume 2, Issue 2 , Winter and Spring 2013, Pages 69-80

Abstract
  In this paper, single, bi-layered and three-layered tube hydroforming processes were numerically simulated using the finite element method. It was found that the final bulges heights resulted from the models were in good agreement with the experimental results. Three types of modeling were kept with ...  Read More
