1. An Investigation in the Deformation Zone of the ECAE Process by the Upper Bound Theorem

MohamadJavad Mirnia; Caren Abrinia; Abbas Rastgoo

Volume 2, Issue 3 , June 2009

Abstract
  In the present paper, the deformation zone of the ECAE (Equal Channel Angular Extrusion) process was investigated using the upper bound theorem. For this purpose, the shape of the streamlines in the deformation zone was assumed to be cubic Bezier curves. Then, the force required for the ECAE process ...  Read More

2. Optimization of the Manufacturing Process of Natural Fibre Thermoplastic Composites in order to Minimize Warpage

Mahmoud Mehrdad Shokrieh; Saman Safari

Volume 2, Issue 3 , June 2009

Abstract
  In this study, the effective factors on warpage in short fibre reinforced thermoplastic composites has been studied. First of all, the effective factors in manufacturing process were detected and then in order to decrease the number of experiments, the approach of Design of Experiments has been applied. ...  Read More

3. Characterization and Determination of Critical Interlaminar Fracture Toughness of Carbon- Epoxy with Arcan Specimen

Masoud Nikbakht; Naghdali Choupani

Volume 2, Issue 3 , June 2009

Abstract
  In recent years, the application of composite materials in aircraft and space vehicle structural components has become increasingly popular. Preventing failure of composite structural systems has been an important issue in engineering design. Due to the lack of through-the-thickness reinforcement, structures ...  Read More

4. Investigating the Effect of Geometric Parameters on the Twist Angle in Roll-Forming of Non-Symmetric Channel Section, Using Finite Element Simulation

Mehdi SalmaniTehrani; Mehdi Nikforouz

Volume 2, Issue 3 , June 2009

Abstract
  Cold roll-forming is a process in which the roll of sheet is formed by passing continuously through the set of rotary rollers without changing thickness in a cool way until it is formed to the desired profile. In this paper a parametric study on the section twist angle in roll-forming the non-symmetric ...  Read More

5. Feature Recognition of Sheet Metal Components and Strip Layout Design in Bending Progressive Dies using Fuzzy Set Theory

Vahid Abedini; Behrouz Arezou; Mohsen Shakeri

Volume 2, Issue 3 , June 2009

Abstract
  Sheet metal components design and manufacture need a great deal of experience and know-how. Strip layout design is usually done with trial and error until best design for strip layout is finally achieved. Knowledge for the system is formulated from plasticity theories, experimental results, and the empirical ...  Read More

In Nano manufacture process the first essential step is modeling coordinately in order to make it available different software are developing for this propose.  In this paper Nano modeling ...  Read More

7. Investigation of Effects of Stress Relieving Parameters on Reduction of Austenitic Spring Free Length During Periodic Loading

Yaser Moghani; Mehdi Ahmadi Najafabadi; Cirus Aghanajafi

Volume 2, Issue 3 , June 2009

Abstract
  After springs production, different residual stresses are created in the inner and outer surfaces of spring wires. Some of these stresses for example compressive residual stresses are useful and some are harmful. The effects of vareation of these stresses are caused spring relaxation and decrising in ...  Read More
